The Indo-Pacific is entering a far more dangerous strategic era. Military modernization, grey-zone coercion, and rapid nuclear expansion are reshaping the regional balance of power. Most notably, China is undertaking a historic expansion of its nuclear arsenal, investing in silo fields, road-mobile intercontinental ballistic missiles, ballistic missile submarines, and dual-capable systems. Simultaneously, Russia’s willingness to use nuclear threats in Europe demonstrates that nuclear coercion is once again central to great-power competition.

In Washington, proposals such as Ely Ratner’s Pacific Defense Pact reflect recognition that the current security architecture is insufficient. A more formalized collective defense structure in the Indo-Pacific is necessary.

However, this is not sufficient. A conventional Pacific Defense Pact does not fully address the most dangerous level of escalation to large-scale conventional war or nuclear attack. What the region now requires is a narrowly defined Indo-Pacific nuclear alliance.

A Narrow, Explicit Purpose

This would not be a sweeping defense pact covering every maritime incident, border clash, cyber intrusion, or grey-zone coercive act. It would have a clear and carefully delimited purpose. That is to deter large-scale conventional war or nuclear attack against member states.

Its clarity would be its strength. That clarity performs a second vital function. It minimizes the risk of entrapment by ensuring member states are not dragged into escalation over actions below the threshold of war. By explicitly excluding grey-zone coercion and limited crises from its nuclear remit, the alliance would reassure leaders that only truly existential threats trigger its highest-level commitments.

Participation becomes politically sustainable and strategically credible because it avoids automatic escalation over incremental provocations. The alliance would draw a line at catastrophic strategic aggression.

The Historical Record: Why Nuclear Deterrence Matters

The case for a nuclear alliance is not theoretical. It is grounded in historical experience. During the Cold War, nuclear parity between the United States and the Soviet Union prevented direct large-scale war and nuclear attack in Europe. Despite ideological confrontation and proxy conflicts, neither side attempted a conventional war or nuclear attack on the other’s core territories. Nuclear weapons imposed restraint. They deterred not just nuclear use, but overwhelming conventional assault.

Similarly, within NATO, the presence of U.S. nuclear guarantees has prevented full-scale Russian conventional attack on Alliance territory. Moscow has tested boundaries through

hybrid tactics and coercive signaling, but it has not launched a large-scale attack on NATO soil. Nuclear deterrence at the alliance level raised the costs to an unacceptable threshold.

The 1969 Sino-Soviet border conflict further illustrates how nuclear capability constrains escalation. The Soviet Union’s nuclear superiority allowed it to signal credible threats, while China’s emerging nuclear capability and mobilization signaled resolve. Mutual fear of escalation compelled negotiation, including intervention through U.S. triangular diplomacy. Nuclear weapons shaped behaviors without being used.

The India–Pakistan experience is equally instructive. Prior to overt nuclearization, the two states fought multiple full-scale wars. Since their nuclear tests in 1998, crises have erupted, but they have remained limited. Missile strikes, cross-border skirmishes, and periods of great tension have not escalated into all-out conventional war or nuclear attack. Nuclear deterrence imposed a ceiling on the conflicts.

Contrast this with the Russia–Ukraine war. Ukraine relinquished its nuclear arsenal in the 1990s and now confronts a nuclear-armed Russia without possessing its own nuclear deterrent. The result has been a prolonged and costly conventional war of attrition. The absence of mutual nuclear deterrence has made sustained large-scale conventional war possible. By comparison, Russia has not launched a direct assault on NATO territory precisely because nuclear deterrence underwrites NATO’s collective defense.

The pattern is clear. Where credible nuclear deterrence exists between adversaries, large-scale conventional war and nuclear attack is sharply constrained or avoided. Where it does not, prolonged and devastating large-scale conventional war and nuclear attack becomes more likely.

The Indo-Pacific Strategic Gap

The Indo-Pacific currently relies on a patchwork of bilateral extended deterrence arrangements centered primarily on Washington. These remain essential, but they are increasingly strained or at risk of being fractured by China.

China’s expanding nuclear arsenal complicates escalation management. A larger and more survivable force reduces the credibility of assumptions that escalation will remain controlled or asymmetrical. Meanwhile, the region contains multiple flashpoints, including Taiwan, the South China Sea, the Korean Peninsula, and the India–China border where conventional conflict could rapidly climb the escalation ladder.

Frameworks like AUKUS and the Quad strengthen capabilities and coordination, while the proposed Pacific Defense Pact aims to guarantee that the U.S. and its allies can act in concert during crises or conflicts. But they are not structured as nuclear deterrence mechanisms. They do not institutionalize shared nuclear declaratory policy, crisis consultation at the strategic level, or joint planning for high-end escalation management. A nuclear alliance would fill that gap.

Beyond a Pacific Defense Pact

A Pacific Defense Pact, as envisioned in conventional terms, strengthens interoperability and signals unity. But without an explicit nuclear dimension, it leaves ambiguity at the highest rung of escalation. That ambiguity can invite miscalculation.

A nuclear alliance would not broaden commitments; it would sharpen them. It would: (1) establish shared declaratory policy on deterrence of large-scale war and nuclear attack, (2) institutionalize strategic consultation mechanisms during crises, (3) coordinate planning to ensure credible escalation management, and (4) reinforce extended deterrence while discouraging independent nuclear proliferation.

Importantly, such an alliance need not require additional states to acquire nuclear weapons. Like NATO, it could rely on extended deterrence commitments and nuclear-sharing with structured burden-sharing and planning arrangements. Nuclear forces may remain nationally controlled, but alliance cohesion amplifies deterrent credibility. 

Clarity as Stability

The objective is not confrontation. It is clarity. By defining a narrow and explicit threshold—large-scale conventional war or nuclear attack—the alliance reduces the risk of catastrophic miscalculation. It signals to potential aggressors that existential aggression will trigger unified strategic consequences.

Simultaneously, it reassures members that lower-level competition will not automatically escalate to nuclear commitments. This dual clarity strengthens deterrence at the top end and stabilizes politics at the lower end.

A Necessary Evolution

The Indo-Pacific is now the central arena of 21st-century strategic competition. Nuclear modernization is accelerating. Multi-nuclear dynamics are emerging. Escalation timelines are compressing.

History shows that nuclear weapons, and when embedded within credible alliance structures, deter catastrophic war. They prevent large-scale conventional war and nuclear attacks not because they are desirable tools of war, but because they impose unacceptable costs on those who contemplate it.

A Pacific Defense Pact is a step forward, but in the current strategic environment, it is not enough. To deter large-scale conventional war and nuclear attack in the Indo-Pacific, the region must move beyond a Pacific Defense Pact. It must build a nuclear alliance.

This was not an isolated incident. Civilian-grade drones and other dual-use technologies are increasingly being used to survey or target public infrastructure. From energy grids to airports, the connective tissue of modern life is exposed to risks once confined to traditional warzones. These developments are reshaping global security policies and blurring the boundary between civilian and military domains.

Civilian Tech, Strategic Impact

Cheap unmanned aircraft systems (UAS) are now accessible worldwide. While drones were initially developed for military use, the most commonly deployed platforms today, such as DJI’s Mavic series, were originally built for civilian applications like aerial photography and videography. Their affordability, portability, and high-spec cameras made them commercially popular, but those same features have made them easy to repurpose for military contexts.

In particular, first-person view (FPV) drones, designed for immersive recreational flying, were rapidly adapted for frontline use in conflict. These drones are now routinely deployed with improvised explosives or used for precision reconnaissance. In Ukraine, both sides repurposed off-the-shelf drones in vast numbers; nearly two million were produced in 2024 alone. Many of these are equipped with AI-enabled navigation and targeting, underscoring how quickly civilian tech can be weaponised.

Non-state actors are following suit. Armed groups are using FPV drones for low-cost, high impact strikes on infrastructure, blurring the lines between military and civilian threats. This second drone age shows that national security vulnerabilities now stem as much from consumer technology as from conventional arsenals.

The broader implication is clear: private-sector innovations, often created without any defense intent, are shaping the battlefield. These companies bring novel use cases, technical advantages, or agile design processes that legacy defense contractors may overlook. Civilian tech is not just a risk; it is a potential strategic asset. Tapping into this ecosystem, especially among start-ups and experts, could redefine how the country protects critical infrastructure in an era of hybrid conflict.

Infrastructure in the Crosshairs

Modern infrastructure is a key target in modern conflicts or hybrid attacks, just like military bases traditionally were. In 2022, after the sabotage of the Nord Stream pipelines, over 70 drone sightings were reported near Norwegian offshore oil platforms. Oslo feared Russian-linked hybrid operations targeting Europe’s energy supply and deployed naval assets and invited NATO allies to assist in patrols.

Meanwhile, Ukraine’s energy grid suffered repeated drone and missile attacks, with waves of low-cost Shahed drones used to disable power plants. By spring 2024, roughly half of Ukraine’s electricity capacity was destroyed, forcing nationwide blackouts.

Outside conflict zones, attacks on infrastructure are also rising. In Sudan, a drone strike on a power station caused regional outages, and other drone attacks on water purification stations left the country on the brink of a significant Cholera outbreak. In the US, federal officials stopped an attack on a power grid by a man using an explosive-carrying drone.

Transportation hubs are vulnerable, too. In January 2025, drone activity shut down Riga Airport, disrupting dozens of flights.

 Gaps in Governance

 Despite growing risks, legal and operational frameworks remain fragmented. Drones and AI-driven surveillance systems often fall outside traditional arms control regimes. As a recent executive order put it, “Criminals, terrorists, and hostile foreign actors have intensified their weaponization of drone technologies, creating new and serious threats to our homeland.”

Jurisdictional confusion is common. In many countries, local authorities lack legal authority to respond to rogue drones above critical sites. Aviation safety rules and privacy laws create hesitation, giving bad actors a head start.

Even when threat awareness exists, coordination is inconsistent. The Cybersecurity and Infrastructure Security Agency warns that drones are used for surveillance and sabotage, yet they lack the comprehensive tools to oversee private-sector resilience or cross-border response.

 A Global Security Challenge

 Drone and AI threats are not confined by borders. In 2023, the European Commission launched a new counter-drone strategy, urging member states to harden infrastructure and coordinate airspace protections. NATO has added counter-UAS exercises to its joint drills, while AUKUS partners are beginning to share emerging drone and AI tactics.

But international law is lagging. There is still no global treaty governing the use of armed drones or autonomous surveillance. Export control regimes struggle to manage proliferation of AI-enabling components. At the UN, efforts to establish binding norms on autonomous weapons are stalled. Ad hoc coordination is, however, slowly improving.

When Norway’s oil platforms were threatened, NATO allies were called in within days. After drone sightings near Dutch and Belgian ports, neighboring governments exchanged countermeasure plans. These models suggest a path forward: rapid and collective responses based on shared tools, shared doctrine, and shared threat intelligence.

The future of civilian dual-use technologies will not be defined by innovators alone. Whether drones or AI software, these tools are already reshaping how adversaries threaten public safety and economic continuity. What is at stake is not just national security, but the resilience of infrastructure that supports daily life.

The Crucial Role of Start-ups in National Defense

 Civilian-origin technologies are now driving the next wave of defense capability. From FPV drones to AI surveillance tools, some of the most disruptive military applications today are emerging not from traditional defense primes but from commercial markets, often developed by start-ups with no military background.

A coordinated international framework is urgently needed, one that does not just support innovation and infrastructure protection but actively integrates civilian tech into defense planning. This means lowering the barriers for experts and start-ups to meaningfully contribute alongside legacy contractors. The United Kingdom’s recent Defence Review hinted at this shift, recognising that smaller firms are vital to national resilience, particularly when civilian infrastructure is under threat.

What is truly needed is a NATO-wide or broader allied framework that enables cross-border collaboration, streamlines regulation, and opens up procurement pathways.

Today, many start-ups working at the intersection of security and technology face steep hurdles: limited access to capital, opaque compliance regimes, and procurement processes designed around, and for, large incumbents. Yet by creating space for their innovation, we can modernize collective defense from the ground up, using the very same civilian tools that adversaries are already turning into weapons.

A coordinated international framework is urgently needed, one that not only supports innovation and infrastructure protection but also lowers barriers to experts and start-ups to contribute more meaningfully alongside traditional defense primes. The UK’s recent Defence Review hinted at this shift, recognizing the value smaller firms bring to national resilience. It is time to take similar action at home.

The United Kingdom’s Defense Issues

The United Kingdom’s military spent several decades downsizing its military. Still, the UK took part in major conflicts in Afghanistan, Iraq, Libya, and Syria, showing that Britain continues to have some force projection capability.

Nevertheless, British Ministry of Defence (MoD) data shows recruitment shortfalls over the past five years. Recent data published by the UK Defence Journal show the biggest recruitment shortfalls are found in the army, where manpower gaps in land forces are most pronounced.

A major factor in recruiting failure was a several-year attempt to draw down spending, that included the army’s closure of half of its recruiting offices, according to the Royal United Services Institute (RUSI). A lack of recruiting offices only erodes the interaction between recruiters and the community. This lack of interaction dissuades civilians, who may not fully understand the benefits of military service, from joining.

Furthermore, an aging population, a rise in health risks, and an extremely long pipeline from recruitment to basic training can dissuade young men and women from choosing service. While Britain’s Air Force and elite Royal Marines remain formidable, further emphasis on naval power and regrowing the land forces is much needed.

Canada’s Rearmament Crisis

The Canadian Armed Forces are currently facing a readiness crisis. According to an internal overview by the Department of National Defence, only 58 percent of the military is ready to handle any situation. Canada’s lack of readiness is increasingly causing concern among the general public. War in Eastern Europe and Africa and brewing conflicts in Asia show the need for North Atlantic Treaty Organization (NATO) member-states to bolster each region. Canada’s military is unready to face a crisis.

A major challenge is stagnation in the Air Force and Navy, where much equipment is neglected and degraded. Because logistics win wars, Canada needs to recruit and train support personnel such as technicians, maintenance, supply, and communications personnel.

Australia’s Defense Issues

Australia, a rising regional power in the Indo-Pacific, also faces challenges for the Australian Defence Forces. Being a member of the trilateral security partnership between Australia, the UK, and the US (AUKUS), Australia is currently awaiting the construction and transfer of three to five Virginia-class submarines from the United States, which may not come in time for Pillar II of the AUKUS agreement, due to stagnant American naval production rates.

Only 80 percent of the 69,000 recruits needed to enhance the Australian Defence Forces have either signed up or met recruiting requirements. Simultaneously, younger Australians feel they have better economic and social opportunities in the private sector than in the military, drawing potential recruits away.

Continuously growing defense spending over several decades will be critical in maintaining readiness. Decades of neglecting defense forced the Australian military into a position where it must catch up to other mid-sized powers like Japan and South Korea. Furthermore, as the Australian Strategic Policy Institute noted, confidence in the military remains low. Thus, efforts to change this view are needed in the information sphere if public institutions are to effectively remilitarize, in lieu of rising threats.

Recommendations for Each Country

The United Kingdom, Canada, and Australia face major recruitment and militarization woes. However, steps can be taken for all three countries to push towards modernization and expansion. This is particularly important if these Anglo nations are to remain a close alliance.

British recruitment woes correlate with the lack of recruitment offices. The British Ministry of Defence must grow and lobby for more offices and events where promising youth can learn and gather information about military service. Furthermore, efforts are needed in the more neglected Royal Navy and Army.

The British have an opportunity to take a leadership position on the continent. Growing the British military will also support defense exports and further enhance and expand the military—albeit with an effort to increase the MOD’s budget.

Canada’s efforts must include broader government support for the military as Canadians question the credibility of a government that drew down the military to ineffectiveness. The Canadian Defence Ministry can also take lessons from NATO partners, such as Poland, Romania, Finland, and others, who are modernizing successfully.

Australia’s expansion of the military must take a two-pronged approach. First, show potential recruits the benefits of military service. Second, the government must instill a sense of patriotism and respect for the Armed Forces. The government can focus on brewing threats in the Indo-Pacific, which will eventually reach Australia, while explaining the benefits of military service.

The Commonwealth countries of the United Kingdom, Australia, and Canada all have capable yet stagnant militaries. Addressing problems with recruitment, logistics, and maintenance can reduce stagnation and help restore these nations’ military strength. As close allies of the United States, their success matters.

Commonwealth Defense and Recruitment Hurdles was originally published on Global Security Review.

While certification is contingent on the US Navy’s ability to maintain its own submarine production rate, which is struggling to meet the planned two Virginia-class submarines per year, Australia would benefit greatly from their acquisition. Overall, it is worth noting that AUKUS Pillar I and Pillar II are likely to significantly enhance US undersea capabilities in the long term. Pillar I includes the rotational presence of one UK Astute-class submarine and up to four US Virginia-class submarines at HMAS Stirling, Western Australia, from 2027. HMAS Stirling provides the United States with greater access for the forward presence of nuclear-powered submarines in the Indo-Pacific.

Indo-Pacific access is further expanded via the new submarine base that is planned for the east coast of Australia by 2043. The authorized consolidated Commonwealth-owned Defence Precinct at Western Australia’s Henderson shipyard will provide contingency-docking and depot-level maintenance for AUKUS submarines by 2033, potentially alleviating some of the burden on US-based maintenance facilities. Pillar II will provide the advanced technology necessary to enhance US, UK, and Australian undersea capabilities, particularly for longer term advantages in mobility, survivability, lethality, and sustainability of allied forces.

Conversely, the SLCM-N is likely a significant factor in retaining American undersea capabilities. The SLCM-N will provide the US with flexible deterrence options in austere Euro-Atlantic and Indo-Pacific theatres, particularly as the US needs to provide extended nuclear deterrence to 32 NATO allies plus Australia, Japan, and South Korea. There are three options to consider when attempting to deter China, North Korea, and Russia.

First, the United States can provide Australia three to five conventionally armed Virginia-class submarines. This option is likely to significantly degrade American undersea capabilities through a lack of flexible response options for strategic deterrence and extended nuclear deterrence. Plus, Australia will need to manage three classes of submarines: the Collins-class, the AUKUS-class, and the SSN-AUKUS under this option.

Second, Australia can field a dual-capable submarines (DCS) mission for Australian Virginia-class submarines. This option requires the establishment of a nuclear planning group (NPG) to plan for a DCS mission for Australian Virginia-class submarines. These submarines would be capable of carrying the SLCM-N. This nuclear-armed option is unlikely to degrade US undersea capabilities, as Australia could support some US missions in the Indo-Pacific and provide flexible deterrence options. Australia will still need to manage three submarine classes under this option.

Third, the United States does not sell Virginia-class submarines to Australia, but instead bases submarines armed with SLCM-N in Australia, either on a permanent or rotational basis. This option does not degrade US undersea capabilities. However, under this option Australia should negotiate for extended nuclear deterrence guarantees. This option is not the end of AUKUS, but Australia will need to build sovereign SSN-AUKUS submarines to fill the gap left by Australia’s aging Collins-class submarines when they are retired.

Policymakers should not be afraid to consider a flexible nuclear-armed option in light of recent and historic Russian and Chinese rhetoric on AUKUS, especially when this rhetoric concerns “non-nuclear long-range precision strike capability.” Having a nuclear-armed option would provide enough flexibility to backstop and limit conventional war.

On April 18, 2025, Russia’s envoy to Indonesia, Sergei Tolchenov, defended military ties with Jakarta and did not deny claims that Russia seeks to station long-range military aircraft at the Manuhua Air Force Base at Biak Numfor, about 1400 kilometers north of Darwin, Australia. Russia asserted that AUKUS is more of a threat to the Asia-Pacific than Russian ties with Indonesia, which are “not aimed against any third countries and poses no threat to security in the Asia-Pacific region.” Tolchenov added that challenges to regional stability

are more likely to arise from the rotational deployment of large military contingents from extra-regional states on Australian territory, including the provision of airfields for the landing of strategic bombers and port infrastructure for visits by nuclear-powered submarines. Particularly alarming are the currently discussed plans to deploy the US intermediate-range missiles in Australia, which would put ASEAN [Association of Southeast Asian Nations] countries, including Indonesia, within its range, as well as the acquisition by the Royal Australian Navy of nuclear-powered submarines under the AUKUS trilateral partnership.

These comments are consistent with Putin’s rhetoric against the North Atlantic Treaty Organization (NATO).

This is not the first time Russia and China accused the US, UK, and Australia of risking an intensified arms race and military confrontation in the Indo-Pacific. A report by the China Arms Control and Disarmament Association, China Nuclear Strategic Planning Research Institute, and the Russian Energy and Security Research Centre stated, “non-nuclear long-range precision strike capability, being provided to Australia, will affect nuclear deterrence and strategic stability.” The report goes on to say that “[w]hile current non-nuclear strategic weapons cannot carry out all the missions assigned to nuclear weapons those still can produce strategic effects.” The report further criticizes AUKUS’ nuclear submarine cooperation, which the report suggests will trigger a regional submarine arms race.

Chinese and Russian threats should not limit or contain AUKUS to non-nuclear options. This is particularly true when the US has historically provided non-nuclear long-range precision-strike capability. In the past this included the F-111 Aardvark, F/A-18F Super Hornet, E/A-18G Growler, and F-35A Lightning II.

Under the UN Charter, members have “the inherent right of individual or collective self-defence if an armed attack occurs.” Hence, Australia and its allies should stand by the expression, si vis pacem, para bellum. Australia and its AUKUS allies should not back down from non-nuclear long-range precision strike capability or nuclear-armed deterrence options that provide more flexible responses.

Although, the sale of Virginia-class submarines to Australia under the AUKUS agreement may be contingent on the US Navy’s ability to maintain its submarine production rate. It is worth noting that American undersea capabilities, particularly in the long term, may be greatly enhanced through other means under AUKUS Pillar I and Pillar II.

In the new era of nuclear disorder, the key to maintaining American undersea capabilities will likely be the SLCM-N deployed on Virginia-class attack submarines. The SLCM-N will provide AUKUS flexible deterrence options and limit risk of conflict in austere Euro-Atlantic and Indo-Pacific theatres.

SLCM-N, the Virginia-Class Submarine, and AUKUS was originally published on Global Security Review.

Secretary Hegseth, a veteran with combat experience in Iraq and Afghanistan, emerged from a military culture defined by counterinsurgency warfare, rapid technological adaptation, and constrained rules of engagement. His formative years were shaped by the leadership of prominent figures like General (Ret.) David Petraeus and General (Ret.) James Mattis, who emphasized adaptive leadership, decisive action, and strategic communication. The norms of that era often prioritized minimizing civilian casualties, leveraging asymmetric warfare, and coalition-based operations. Given this background, Hegseth’s emphasis on restoring a warrior ethos and projecting unyielding strength likely stems from his own military experiences and the influential leaders who shaped his perspective.

Hegseth’s message signals a deliberate shift away from the strategic ambiguity that may embolden adversaries. The emphasis on deterrence through strength suggests a belief that Russia’s nuclear brinkmanship, China’s rapid arsenal expansion, and North Korea’s unpredictability stem from a perception of American hesitancy. One might observe that the concept of strategic ambiguity, once hailed as a nuanced tool of deterrence, now appears as outdated as the punch-card computers that once calculated nuclear trajectories.

This shift reflects a growing concern about the credibility of extended deterrence and the need for more explicit signaling of American resolve. By modernizing the nuclear triad and reaffirming America’s willingness to use force, the Pentagon aims to reinstate fear as a core pillar of deterrence.

The emphasis on reviving the warrior ethos implies that nuclear deterrence must be as much about mindset as it is about capability. It is striking to note that the last time a Secretary of Defense emphasized a similar warrior ethos, the world was still reeling from the Cuban Missile Crisis, a stark reminder of the high stakes involved. The focus on a warfighting mentality suggests a move away from the bureaucratic approach that dominated nuclear policy in recent decades. It is a move toward a more operational and combat-focused posture.

The intent may be to move away from a risk-averse approach, ensuring that warfighters at all levels understand nuclear deterrence as an active, rather than passive, responsibility. This shift could result in more frequent readiness drills, a recalibration of nuclear employment thresholds, and strategic force posturing that prioritizes offensive capabilities over restraint.

China is projected to reach nuclear parity with the US by 2035, while Russia continues aggressive arsenal expansion and hybrid warfare tactics. Hegseth’s directive appears motivated by a desire to prevent a world where nuclear deterrence is no longer dictated by American supremacy. This shift away from the established norms of strategic restraint is a necessary adaptation to a multipolar world, or it could be a dangerous escalation that precipitates a new arms race.

There is an inherent tension between maintaining strategic dominance and fostering international stability. Modernization efforts—accelerated intercontinental ballistic missile production, hypersonic weapons, and a stronger nuclear-capable bomber fleet—align with an intent to sustain America’s dominant position before near-peer threats fully materialize.

The call to rebuild the military by rapidly fielding emerging technologies may suggest a strategic push toward AI tools that enable improved nuclear command and control, quantum-resistant encryption, and space-based early warning systems. The intent behind these investments appears twofold. First, there is a desire to ensure American nuclear forces cannot be neutralized by cyber, space, or electronic warfare. Second, there is a desire to establish deterrence dominance through superior technological integration before adversaries close the gap.

If this is a return to a bold, George S. Patton-style of leadership, where decisive action and unwavering resolve are paramount, it could also risk a dangerous overemphasis on military solutions at the expense of diplomacy. This approach raises crucial questions about the balance between technological innovation and strategic prudence.

Hegseth’s message reaffirms commitment to American allies, signaling that extended deterrence remains a central policy. The intent appears to be preempting concerns of American disengagement from NATO and Indo-Pacific security commitments while simultaneously warning adversaries, especially China, that American nuclear resolve is non-negotiable. Some may assume that a more aggressive posture inherently breeds instability, paradoxically, it could also create a more stable balance of power by clearly defining red lines and deterring potential aggression.

This strategy hinges on the assumption that adversaries will respond rationally to demonstrations of force. This could translate into increased nuclear deployments to allied territories; stronger trilateral deterrence initiatives between the US, UK, and Australia (AUKUS); and a renewed focus on NATO’s nuclear-sharing agreements to counter Russian regional threats.

Secretary Hegseth’s “Message to the Force” signals an intentional and urgent shift in US nuclear strategy—one motivated by a belief that deterrence is eroding and must be aggressively rebuilt. Whether through new weapons systems, a hardened warrior mindset, or the integration of cutting-edge technology, the modernization push under his tenure will likely define the next era of American nuclear policy.

Deterrence Down Under Podcast: Wargaming-A Strategic Tool for Defence with Darren Huxley and John McGarry was originally published on Global Security Review.

In this episode, Christine and Natalie engage with Dr. Mariana Budjeryn, a nuclear historian, to discuss her book ‘Inheriting the Bomb’ and the complexities surrounding Ukraine’s nuclear disarmament. They explore the historical context of Ukraine’s nuclear arsenal, the narratives surrounding its disarmament, and the implications of security assurances from major powers. Mariana shares her personal reflections on the ongoing war in Ukraine, the challenges faced by nuclear facilities under occupation, and the lessons learned for international security and cooperation.

Podcast: The Complexities of Ukraine’s Nuclear Legacy was originally published on Global Security Review.

They continue similar priorities and themes to the previous coalition government’s 2020 Defence Strategic Update and Force Structure Plan on the space domain. As with those documents, the 2024 NDS and IIP highlight the importance of space as a critical enabler for terrestrial military operations and an operational domain in a multi-domain approach to a strategy of deterrence by denial.

Furthermore, they identify three broad capability areas for further development.  These include (1) the provision of space support, notably through satellite communications to be provided by Australian-owned satellites through project JP9102 in geosynchronous orbit; (2) the establishment of enhanced space domain awareness, with the establishment of a Deep Space Advanced Radar Capability (DARC) at Exmouth in Western Australia—part of a global network of three such sensors—in collaboration with the US and UK; and (3) the development of space control capabilities.

This last aspect of the NDS and IIP opens some intriguing possibilities for future development that could be announced in subsequent policy documents, with the next NDS and IIP due in 2026. It also raises the possibility that space could start to play a larger role as a priority area in AUKUS Pillar 2. Already, the agreement to establish DARC is seen as part of AUKUS and will extend Australia’s ability to undertake space domain awareness out to geosynchronous orbit (GEO) at 36,500 kilometers. That complements the existing C-Band radar and space surveillance telescope already located at Exmouth and will dramatically enhance the ability of Australia to undertake space surveillance under Operation Dyurra. This is an essential requirement for Australia to undertake the space control mission, so it would make sense to bring this role into AUKUS Pillar 2 as well and see the two missions as integrated.

Just how Australia will undertake space control needs further clarification. There is only the following paragraph in the IIP, which states that space control will include “measures to enhance Defence’s space control capability to deny attempts to interfere with, or attack, Australia’s use of the space domain. These will help ensure the ADF is able to continue using the space capabilities it needs to support its operations.”

Australia has signed the ban on undertaking destructive testing of direct-ascent anti-satellite (ASAT) weapons as part of steps to promote responsible action in space, and it is extremely unlikely that Australia would pursue destructive “kinetic kill”’ ASATs, either direct-ascent or co-orbital in design. Exactly what Australia could pursue in terms of space control is open to speculation at this stage. Defence has undertaken work toward a space-electronic warfare capability under Defence Project DEF 9358, and this would be consistent with the 2024 IIP’s stated approach to space control, as well as the 2020 Force Structure Plan.

A “soft kill” capability, which is either ground-based or co-orbital, that could deliver scalable and reversible effects without creating space debris would contribute directly to the need for space control in a manner that is also consistent with Australian approaches to responsible actions in space. In the same way, other non-kinetic approaches—directed-energy or cyber—might open up opportunities for Australia to develop space control in the future.

The 2022 Defence Space Strategy, released by Defence Space Command, makes clear the importance of assured access to space. This can be achieved in part through resilience of space support, including through defending satellites on-orbit via space control. But it also can be strengthened through enhancing sovereign launch capability. It is in this area where the 2024 NDS and IIP misses a valuable opportunity to integrate the space needs of defense with the growing commercial space sector.

There is no mention whatsoever of Australia’s vibrant commercial space sector in the 2024 NDS and IIP. It is almost as if the view from Defence is that this growing sector does not exist. Yet, Australia’s space sector is fast emerging as the basis for an end-to-end ecosystem, comprising not only the ground segment, but also satellite design and manufacturing through to sovereign launch capabilities.

Indeed, Australia is truly blessed in geographic terms for sovereign launch, with launch sites in the north located close to the equator to take full advantage of Earth’s rotational energy for cheaper cost per kilogram into equatorial low-earth orbit, and launch sites along the south of the continent that are well placed to access polar and sun synchronous orbits. Australia’s launch geography is a key factor prompting the signing of a Technology Safeguards Agreement with the United States on launches and returns.

Defence missed this opportunity to strengthen space resilience through supporting sovereign launch of small satellites that could complement large satellites in GEO, such as those envisaged for JP9102 with proliferated LEO (pLEO) constellations of small satellites for satellite communications and earth observation, to support both civil and defense needs. It missed the clear benefits of sovereign launch to reinforce assured access to space, through rapid augmentation of existing space capabilities in a crisis—or reconstitution of those capabilities in the event of an adversary employing counterspace capabilities against Australian satellites. It missed the opportunity for Australia to take a new step forward to do more to burden share in orbit with allies and strengthen the resilience of space support in the face of counterspace threats from China and Russia.

As the NDS and IIP are biennial documents, the opportunity is still there for Defence to embrace a bolder vision for Australia in space in the next release in 2026, whilst government more fully supports the growth of the commercial space sector. The question is whether Defence and the government will have the vision and determination to do something new. They have begun to think in these terms, given their support for developing space control capabilities, but they can do so much more.
