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.

That gap undermines American extended deterrence because Washington cannot reassure allies or deter aggressors without accounting for South Asia’s threat calculus. AI arms developments in this region stem from colonial legacies and mistrust of great power intentions, creating a volatile strategic environment.

India’s Governance Innovation in Defense AI

India’s governance model integrates civilian oversight with defense research and ensures ethical deployment of AI. The Responsible AI Certification Pilot evaluated algorithms for explainability before clearance. Its National Strategy for AI mandates ethical review boards for dual-use systems. Developers must document bias-mitigation measures and escalation pathways. Embedding accountability at design phase stabilizes deterrence signals by reducing inadvertent algorithmic behaviors.

The Evaluating Trustworthy AI (ETAI) Framework advances defense AI governance. It enforces five principles: reliability, security, transparency, fairness, privacy, and sets rigorous criteria for system assessment. Chief of Defense, Staff General Anil Chauhan, stressed resilience against adversarial attacks, highlighting the challenge of balancing effectiveness and safety. By mandating continuous validation against evolving threat scenarios, ETAI prevents mission creep and maintains operational integrity under stress.

India’s dual use by design philosophy embeds safeguards within prototypes from inception. This contrasts with reactive models that regulate AI after deployment. Civilian launch-authorization channels separate political intent from technical execution, ensuring decisions remain under human control and reinforcing credibility in crisis moments. Regular red-team exercises involving independent experts further validate system robustness and reduce risks of false positives in autonomous targeting.

Strengthening Extended Deterrence through Cooperation

US-India collaboration on AI verification can reinforce extended deterrence by aligning technical standards and testing protocols. The iCET fact sheet outlines secure information sharing and joint safety trials. Launched in January 2023, iCET has already enabled co-production of jet engines and transfer of advanced drone technologies. Building on this foundation, specialized working groups could develop common benchmarks for adversarial-resistance testing and automated anomaly detection.

A Center for Strategic and International Studies report recommends a trilateral verification cell blending American evaluation tools with India’s ethical reviews. Joint trials of autonomous air-defense algorithms would demonstrate interoperability and resolve. A shared “AI Red Flag” system would alert capitals to anomalous behaviors and reduce strategic surprise. Embedding cryptographically secure logging of decision path data ensures an immutable audit trail for post-event analysis and confidence building.

The INDUS-X initiative, launched during Prime Minister Narendra Modi’s 2023 US visit, integrates responsible AI principles into defense innovation. By aligning standards, both countries ensure AI systems enhance strategic stability rather than undermine it. Expanding INDUS-X to include scenario-based wargaming with allied partners can stress-test ethical frameworks and calibrate thresholds for human intervention under duress. This model can extend under the Quad framework, pressuring authoritarian regimes to adopt transparency measures.

Institutionalizing Global AI Arms Control

A formal arms control dialogue should adopt India’s baseline standards for ethical AI governance. The UNIDIR report calls for universal bias audits and incident-reporting obligations to prevent unintended escalation. Carnegie scholars propose a tiered certification process under a new protocol for autonomous systems within the Convention on Certain Conventional Weapons, requiring peer review of algorithms before deployment. Embedding such certification in national export-control regimes would create global incentives for adherence.

The UN General Assembly has established an Independent AI Scientific Panel and a Global Dialogue on AI Governance to issue annual assessments on risks and norms. This mechanism can evaluate military AI applications and recommend confidence-building measures. Procedural transparency would coexist with confidentiality requirements, balancing security with mutual reassurance. Regular joint workshops on risk-assessment methodologies can diffuse best practices and diffuse mistrust among major powers.

Regional Applications and Future Prospects

India’s responsible AI framework must inspire regional adoption and confidence-building measures. Pakistan and China should engage transparency initiatives to prevent dangerous asymmetries in AI capabilities. Proposed measures include joint research on AI safety, shared performance databases, and collaborative development of detection algorithms.

Successful tests of India’s hypersonic ET-LDHCM system, capable of Mach 8 and a 1,500-kilometer range, underscore the urgency of governance frameworks before fully autonomous weapons deploy. The Quad’s model of Indo-Pacific cooperation provides a template for multilateral norms on responsible AI in defense. Extending these norms to confidence-building measures such as pre-deployment notifications and automated backchannels can reduce the risk of inadvertent escalation.

Looking ahead to the United Nations General Assembly meeting on AI governance in September 2024, American policymakers can leverage India’s experience. Joint verification exercises and an ethical audit regime will establish global norms for military AI. Integrating lessons from ETAI and iCET into the assembly’s resolutions can produce enforceable standards that bind both democratic and authoritarian states. This approach will reaffirm American extended deterrence and help prevent destabilizing AI-driven arms races worldwide.

By demonstrating that ethical AI development strengthens rather than weakens deterrence credibility, India’s model provides both technical solutions and normative frameworks for managing the military applications of artificial intelligence. Sustained international cooperation on these principles is pivotal for securing strategic stability in a rapidly evolving technological landscape.

The challenge is clear; adversaries are developing ASAT weapons, electronic warfare capabilities, and cyber threats that can disable American satellites—disrupting military operations, global communications, and economic stability. Without a robust deterrence framework, adversaries are emboldened to target space infrastructure. To counter these threats, the US must enhance resilient space architectures, strengthen policy frameworks, and refine operational doctrine to deter and, if necessary, defeat adversarial actions in space.

Resilient Space Architectures: Hardening the Backbone of American Space Operations

One of the most effective deterrence measures is making space assets more difficult to target and replaceable, if attacked. The United States is shifting from large, centralized satellite systems to disaggregated and proliferated constellations, reducing the risk posed by any single point of failure. The Proliferated Warfighter Space Architecture (PWSA), led by the Space Development Agency, aims to deploy a network of small, low-cost satellites that provide redundancy, making it harder for adversaries to cripple American space capabilities with a single strike.

Additionally, on-orbit servicing, maneuverable satellites, and rapid launch capabilities enhance resilience. SpaceX’s Starlink and the Rapid Agile Launch Initiative ensure that the US can quickly replenish space assets, denying adversaries the ability to achieve lasting effects through space attacks. By maintaining a dynamic, self-healing space architecture, the US strengthens deterrence by signaling that any attempted disruption will be ineffective.

Counterspace Capabilities: Strengthening Active and Passive Defenses

While resilience is key, deterrence also requires credible counterspace capabilities to impose costs on adversaries. The US Space Force and other defense agencies are investing in defensive counterspace measures, such as jamming-resistant communications, maneuverable satellites, and cyber-hardened space systems to protect critical assets.

At the same time, the US must maintain offensive counterspace capabilities as part of a deterrence posture. This includes electronic warfare tools to disrupt enemy satellite operations, rendezvous and proximity operations (RPO) for on-orbit inspection and intervention, and ground-based kinetic and non-kinetic capabilities to neutralize hostile space threats. By demonstrating both defensive resilience and credible response options, the US reinforces deterrence by denial and punishment.

Policy and Alliances: Strengthening Space Norms and Collective Security

A strong policy framework and allied cooperation bolster deterrence by shaping adversary behavior and reinforcing international stability. The Artemis Accords, a multinational agreement on responsible space conduct, establish norms that promote transparency and discourage hostile activities. The US must continue leading diplomatic efforts to build consensus on space security standards, making aggressive actions politically and strategically costly for adversaries.

Additionally, alliances like the North Atlantic Treaty Organization (NATO), partnership with the Quad (Australia, India, Japan, and the US), and Five Eyes intelligence network provide collective security in space. The Combined Space Operations (CSpO) initiative, which includes Australia, Canada, France, Germany, New Zealand, the UK, and the US, enhances shared situational awareness and rapid coordination in space crisis scenarios. By integrating allied capabilities, the US deters adversaries by presenting a unified, multinational response to any hostile space activity.

Space Domain Awareness: Gaining the Tactical Advantage

Deterrence depends on knowing when and where threats emerge. The US Space Force and the National Reconnaissance Office (NRO) are advancing Space Domain Awareness (SDA) through advanced radar systems, AI-powered surveillance, and persistent monitoring of space objects. Programs like the Deep Space Advanced Radar Concept (DARC) and the Space Surveillance Telescope provide real-time tracking of adversary satellite maneuvers, ensuring that hostile actions do not go undetected.

By integrating AI and machine learning, the US can predict and respond to potential threats before they escalate. Improved SDA capabilities deny adversaries the element of surprise, reinforcing deterrence by ensuring that any aggressive move is immediately identified and countered.

Military Space Operations: Defining Rules of Engagement

To deter and defeat adversary actions, the US must develop clear space warfighting doctrine and operational concepts. The Space Force’s “competitive endurance” strategy emphasizes continuous engagement with adversaries to counter gray zone tactics, such as cyber intrusions, satellite blinding, and electromagnetic interference. Establishing clear rules of engagement for responding to hostile actions in space strengthens deterrence by ensuring decisive and proportional responses when necessary.

Additionally, the integration of space with multi-domain operations ensures that any adversary attack on space assets is met with cross-domain retaliation, whether in cyber, air, land, or sea. This raises the stakes for adversaries, reinforcing deterrence by making space conflict an unattractive option.

Conclusion: A Comprehensive Approach to Space Deterrence

The US must pursue a multi-layered strategy to deter and defeat adversary actions in space. Resilient architectures, credible counterspace capabilities, strong alliances, superior space domain awareness, and well-defined military operations are essential to ensuring freedom of action in space and securing national security interests. As space becomes increasingly contested, the ability to deter, detect, and defeat threats will determine whether the US maintains its strategic advantage beyond the atmosphere.

Beyond the Atmosphere: Strengthening US Space Deterrence in a Contested Domain was originally published on Global Security Review.

President Trump’s foreign policy will primarily focus outside South Asia and engage countries with a lens toward their relationship with China. Drawing on his known foreign policy orientation, Trump 2.0 is poised to keep India on a high strategic pedestal in the broader framework of Indo-Pacific strategy.

Pakistan is unlikely to play a major foreign policy role for the Trump administration. Thus, it is pertinent for the Pakistani diplomatic community to find areas of convergence with the Trump administration. Policy options must be exercised in a way to constructively approach strategic divergencies between the two states.

America’s engagement with the Global South is likely going to decline as an “America First” approach calls for reducing international engagement towards all but a handful of countries. Critics may characterize President Trump’s foreign policy approach as short term and transactional, but this sells the president short. A policy of “minilateralism” is not shortsighted but may allow him to focus on more pressing domestic issues in the United States. This redirection of focus is, however, bad news for global agendas like climate change and multilateral cooperation.

There is a broader consensus in the Trump team, based on a strategic imperative to counter China in the Asia-Pacific, that leaves less room for lower priorities. Thus, the trade and tariff wars between China and the US may have second-order effects for countries like Pakistan.

President Trump’s advisers are likely to approach China as an adversary and will view Pakistan with some caution, perceiving it as an ally of Beijing. The Trump administration may seek to intensify the competition with China and up the ante for countries who are onboard with Chinese infrastructure and development projects, such as Pakistan, which could be a potential victim of a new Great Game.

An era of conditional trade agreements between Pakistan and the United States appears imminent and is characterized by a departure from preferential trade practices. Instead, the US is likely to prioritize market-driven agreements, emphasizing economic pragmatism over diplomatic goodwill. To enhance bilateral trade relations, Pakistan could strategically leverage its geopolitical significance and pursue a proactive approach to addressing American concerns, without compromising its national strategic interests.

This would necessitate credible efforts to combat terrorism and contribute to stabilizing the situation in Afghanistan. Such measures could foster greater mutual confidence and pave the way for more constructive economic engagement between the two nations.

American attempts to make India its strategic surrogate in the Asia-Pacific will embolden Indian hegemonic ambitions. Intense security collaboration between the US and India at bilateral and multilateral defense groups like the Quad could disrupt the regional strategic stability calculus in South Asia.

Pakistan’s economic woes may not allow it to sustain the brunt of a growing Indian strategic modernization in the long run. This will impact strategic stability in the region.
Retrospective analysis of the first Trump administration suggests that American cooperation with Pakistan, in the realms of climate change and clean energy, will be relegated as more pressing geostrategic issues take precedence. Moreover, the dwindling economy of Pakistan may find the Trump administration far less sympathetic as far as economic aid and loan packages are concerned. The first Trump administration was less sensitive to Pakistan’s core interest, like Kashmir, and more demanding of Pakistan in its Afghanistan conundrum.
The US State Department under Trump will likely pursue a limited set of priorities, especially in the security and counterterrorism realms. US-Pakistan relations are traditionally marked by events in Afghanistan. This was true from the Soviet invasion of Afghanistan to the war on terror. With the reduction of American engagement in Afghanistan, Pakistan finds itself entangled in an increasingly intricate security matrix amid deteriorating relations with the Taliban and increasing terrorism in Pakistan.

Shifting the onus onto Pakistan for an American policy debacle was a convenient strategy of the Biden administration. Pakistan may find the new administration more aggressive in its demands for stabilizing Afghanistan. The “do more” mantra will not go over well with Pakistan anymore and will require a more practical approach on the part of the US.
On the flip side, President Trump’s personality-centered diplomatic overtures, rather than institutionalized mechanisms, are not good for Pakistan. President Trump engaged with Imran Khan constructively, but he is no longer in office. Criticism could come from Trump’s team regarding the crackdown on Khan’s Pakistan Tehreek-e-Insaf (PTI) movement. State Department and Pentagon engagement with Pakistan’s diplomatic corps and security establishment will depend on the whims of Trump rather than an ongoing policy framework. The absence of mutual interests between the US and Pakistan remains a hurdle.

These are interesting times for the diplomats of Pakistan. On the one hand, they will try to resist President Trump’s pressure-based strategy toward Pakistan. On the other hand, they will try to convince State Department officials to pursue more practical approaches to the US-Pakistan relationship. How hard this proves is yet to be determined.
Either way, Pakistan will face a more conditional and transactional relationship with the US. It will hinge on security concerns rather than economic issues. Being close to China diplomatically and strategically opens a unique window of opportunity for Pakistan. It can play the role of a bridge between China and the US, as it has done historically, should the Trump administration seek it out.
