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One might observe that the concept of strategic ambiguity, once hailed as a nuanced tool of deterrence, now appears as outdated as the punch-card computers that once calculated nuclear trajectories.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.

Hegseth’s Doctrine: A Rebirth and Redefinition of American Deterrence? was originally published on Global Security Review.

Informed by the works of Lieutenant General Tom D. Miller, particularly “The Defense Sustainment Industrial Base” and “Capability, Capacity, and Risk in Sustainment of Air Force Weapon Systems,” it is clear that the challenges and strategies surrounding maintenance of Air Force weapon systems are multifaceted. The first article highlights the foundational elements necessary for a robust defense sustainment industrial base, emphasizing the need for a resilient infrastructure. The second publication further develops this analysis, delving into the evolving landscape of capability, capacity, and risk management in the context of sustaining advanced weapon systems. Collectively, these works offer critical insights and recommendations on optimizing the sustainment process, ensuring readiness and effectiveness in a changing security landscape.

This passage highlights a significant juxtaposition of key themes present in the Secretary of Defense’s goals and Gen. Miller’s examination of Air Force sustainment challenges. To navigate these challenges effectively, specific focus must be placed on three pivotal areas: restoring the warrior ethos, rebuilding the military, and reestablishing deterrence.

In the effort to restore the warrior ethos, the military needs skilled personnel, modern facilities, and a sustainable defense industrial base. Workforce retention and a shortage of technical expertise undeniably impact operational readiness. According to the Secretary of Defense’s mandate, there is a pressing need to “revive the warrior ethos and restore trust in our military.”

Miller’s analysis reveals that the sustainment workforce is facing severe challenges such as an aging workforce, a lack of recruitment, and significant technical expertise gaps. The Air Force Sustainment Center (AFSC) is currently experiencing a 30 percent shortage in experienced depot maintenance personnel. This shortfall adversely affects the maintenance and throughput of mission-critical aircraft. A 2022 report by the Government Accountability Office (GAO) reported that workforce shortages at Air Logistics Complexes (ALCs) contribute to an average delay of 20 percent in aircraft depot maintenance cycles, diminishing operational readiness.

Transitioning from a counterterrorism focus to one that emphasizes great power competition necessitates a sustainment workforce capable of advanced manufacturing and software maintenance, but current training pipelines struggle to produce such expertise. The implications are stark; a degraded sustainment workforce directly undermines operational readiness, particularly in maintaining high-end platforms like the F-35, which are essential for effective deterrence.

In relation to rebuilding the military, the defense industrial base faces significant hurdles due to aging infrastructure, inefficient procurement processes, and inconsistent funding. Secretary Hegseth emphasizes the importance of this rebuilding process, stating the need to match threats with capabilities. Gen. Miller’s assessments indicate that the Air Force’s sustainment infrastructure is outdated and that funding for depot modernization is inconsistent. The average age of Air Force maintenance depots exceeds 60 years, with several facilities dating back to World War II. Supply-chain vulnerabilities also arise. Significant dependence on a sole supplier for 67 percent of critical spare parts for legacy aircraft creates potential crises during conflicts. Moreover, extended procurement cycles often delay readiness enhancements, averaging 8 to 10 years from requirement to fielding for sustainment modernization projects.

Thus, without rapid modernization of sustainment infrastructure and necessary acquisition reform, the Air Force will struggle to maintain aging fleets while simultaneously integrating essential next-generation capabilities for initiatives like joint all-domain command and control (JADC2) and agile combat employment (ACE).

Reestablishing deterrence requires a comprehensive assessment of readiness to ensure that sustainment capacity effectively aligns with the threats posed by nations such as China and Russia. As stated in the SECDEF mandates, deterrence must be reestablished through defense of the homeland and collaboration with allies. However, Miller’s 2022 assessment points out a disconnect between current sustainment funding models and the operational requirements of deterrence in contested environments. For instance, from 2012 to 2022, the readiness rates for the USAF fighter fleet plummeted from 75 to 57 percent, with sustainment backlogs contributing significantly to non-mission-capable status. Only 40 percent of American sustainment infrastructure is currently forward-positioned in the Indo-Pacific, which is crucial for countering aggressive actions from adversaries.

To counter these challenges and bolster national defense strategy, courses of action should be implemented. First, revitalizing the sustainment workforce through expanded training and technological improvements is essential. According to projected outcomes, this could reduce depot maintenance delays by 15 to 20 percent within five years while raising mission-capable rates for advanced platforms.

Second, prioritizing infrastructure and acquisition reform will require streamlining procurement processes and integrating industry best practices. This reform could lead to a reduction in aircraft downtime and enhance rapid repair capabilities essential for operating within geographic regions such as the Indo-Pacific. Finally, adopting a risk-based resource-allocation strategy aligned with high-threat mission areas can significantly strengthen deterrence, ultimately raising mission-capable rates of critical platforms.

By aligning sustainment actions with the objectives of the National Defense Strategy, the Air Force can demonstrate improved deterrence capabilities, build enduring advantages, and modernize its force. An immediate investment in revitalizing the sustainment workforce, modernizing depot infrastructure, and aligning resources with operational needs is imperative. A reformative approach to sustainment is not merely an operational necessity; it constitutes a vital aspect of maintaining peace through strength. Without these necessary adjustments, the Air Force risks facing severe mission degradation in high-threat scenarios, ultimately jeopardizing national defense.

Achieving Peace Through Strength: A Sustainment Imperative was originally published on Global Security Review.

This captures the essence of the doctrine of “peace through strength.” As President Trump described during the commander-in-chief inaugural ball, “We will measure our success not only by the battles we win but also by the wars we end—and perhaps most importantly, the wars we never get into. It’s called peace through strength. Through our power and might, we will lead the world to peace, our friends will respect us, our enemies will fear us, and the whole world will admire the unrivaled greatness of the United States military.”

“Peace through strength” refers to accumulating and displaying forms of national power to create a favorable international environment. The phrase originates from the Roman Emperor Hadrian, who said, “Seek peace through strength, or failing that, peace through threat.” This concept shaped the strategy and goals of Western deterrence during the Cold War and should today. While America squandered its deterrence capabilities, its adversaries relentlessly pursued a deliberate strategy of “subjugation through intimidation.”

The ripening entente between Russia and China, alongside the alarming rate of their expanding and diversifying nuclear arsenals, is further complicated by an expanding North Korean nuclear capability. A collaborative campaign of deliberate and opportunistic aggression fueled by revisionist ambitions torments the South China Sea, is devastating Ukraine, and threatens Taiwan. These malcontent states seek to sow chaos, undermining the existing international order by altering its rules, resource distribution, recognition, territorial boundaries, and economic dominance. To impede these “mavens of malice,” the USA will need to rely on its most formidable hard-power option––nuclear weapons.

Secretary Hegseth must drive the urgent regeneration of America’s nuclear deterrence capability and credibility. This will require an expanded and more capable American nuclear arsenal to effectively counter the mavens’ growing forces. The ongoing $1.1 trillion nuclear enterprise modernization, designed to meet the previous decade’s threat, is plagued by delays in nearly every major system and is insufficient to meet the growing threat of the next decade. The United States requires additional nuclear capacity to ensure deterrence tomorrow. Here are four proposals that President Trump and Secretary Hegseth could initiate tomorrow to enhance the warrior ethos and strengthen deterrence.

First, the United States should suspend participation in New START, as Russia did in February 2023. Regardless of Putin’s grievances, Russia’s actions purposefully undermine the rules-based international order. Given Russia’s consistent history of treaty violations, China’s violation of Article VI of the Nuclear Non-Proliferation Treaty (NPT), and recent revelations Moscow exceeded New START warhead limits in 2024, new arms control treaties are unlikely for the foreseeable future. Moscow perceives military and political advantage by not engaging in these matters, instead pursuing escalation dominance without fear of American reprisal. Participating in any treaty alone devalues the treaty process and demeans American credibility.

Second, the US must immediately cease all warhead dismantlement and begin urgent refurbishment of the remaining 2,000 retired warheads. The provisions of the 2025 National Defense Authorization Act, including salvaging B83 nuclear bombs and W72-2 warheads from retirement, must be implemented immediately. In conjunction with the 2023 decision to build a B61-13, the president should direct the reconditioning and deployment of every weapon in the active and inactive stockpiles to achieve full mission capability as soon as possible.

Third, the president should promptly adjust the posture of America’s current nuclear forces to strengthen deterrence. This includes redeploying stored warheads to re-MIRV the Minuteman III with three warheads per missile—as recently advised by US Strategic Command’s commander, General Anthony Cotton. Adding nearly 800 warheads demonstrates American resolve in the face of China’s and Russia’s nuclear modernization and expansion to reassure allies whose populations contemplate acquiring their own nuclear forces.

Reconfiguring denuclearized bombers to a nuclear-capable configuration and returning bombers to nuclear alert status is critical—with one-fourth of bombers postured for rapid takeoff to ensure survival. Dispersed bombers and supporting tanker aircraft on alert ensure a robust second-strike bomber capability, essential for credible deterrence, preserve employment options for the president, and complicate adversary targeting.

Adversaries cannot believe they can disrupt the crucial detect-decide-direct command and control chain necessary to respond to a nuclear first strike. They must never believe that a decapitating first strike could stop American retaliation. Therefore, alternative and mobile command centers should be continuously enhanced, staffed, and mobilized.

Fourth, rapidly deploying a sea-launched nuclear cruise missile (such as the TLAM-N or SLCM-N) is essential to counter the significant non-strategic nuclear weapons advantage held by both China and Russia. Former Secretary of Defense Casper Weinberger’s report emphasized these systems’ significance over four decades ago. Since 1984, the US regarded nuclear SLCMs on submarines and surface ships as cost-effective and operationally efficient options against a wide range of targets.

Weinberger favored nuclear SLCMs across multiple vessel types to complicate an attacker’s planning and enhance overall survivability of the force. At a minimum, the Navy’s four Ohio-Class guided-missile nuclear submarines could be rearmed with refurbished TLAM-N nuclear cruise missiles that retired from service around 2011. This would enhance the potential at-sea deterrent by 28 percent until the future SLCM-N comes online. Deployment of larger numbers of SLCMs will dramatically increase the size of the survivable sea-based deterrent and provide a viable nuclear-limited strike capability.

Increasing the number of bombers, missiles, and warheads in the active force enhances American military capabilities. Once removed from the constraints of New START, the Ohio-class submarines could be restored to their original capacity of 24 missile tubes, adding 56 submarine-launched (MIRVed) ballistic missiles. B-1 bombers should be retained rather than retired and reconfigured for nuclear operations to meet nuclear and conventional demands on an overburdened bomber force.

With global tensions escalating, the United States must reclaim its position of strength to maintain the peace through a powerful deterrent. Only swift and decisive action can preserve national security and safeguard the global order America forged. The strategic challenges presented by these mavens of malice demand the United States urgently strengthen its nuclear deterrent. Secretary Hegseth inherited a sluggish modernization effort that will not “go faster”––unless it becomes a national priority.

A peace through strength doctrine urgently requires increased capacity and enhanced readiness. Suspending New START participation and returning to a pre-1991 deterrence posture sends a clear message. Any attempt to subvert the global order or threaten American interests will be met with resolute and overwhelming force.
