The credibility of the nation’s nuclear deterrent, the ultimate guarantor of sovereignty, is inextricably linked to domestic well-being. Economic prosperity, social cohesion, and the trust citizens have in their institutions are all part of that amorphous concept. Adversaries like Russia and China understand that it is in their interest to undermine American societal health; it is time Americans realize the challenge facing the nation.

For decades, the logic of nuclear deterrence rested on a triad of capabilities, credibility, and communication. The United States fielded the world’s most advanced nuclear arsenal and communicated credibility effectively. But credibility—the unwavering belief in America’s will to act—is the lynchpin.

This is where the home front becomes the front line. A nation that is prosperous, unified, and optimistic possesses the strategic endurance to maintain its commitments. Societal well-being is not a “soft” issue separate from “hard” power; it is a foundational strategic asset that fuels long-term political resolve.

The mechanisms connecting a healthy society to a credible deterrent are not merely theoretical. They are etched into recent history. Consider the 1980s under President Reagan. An economic resurgence and a renewed sense of national confidence provided the political capital and financial resources for a sweeping modernization of nuclear forces that saw the Peacekeeper ICBM and the B-2 stealth bomber enter service.

This was not just a military build-up; it was a clear signal to the Soviet Union, born from a nation that had the resources and the will to compete over the long haul. High public trust, buoyed by economic stability, sustained the political commitment for these massive, multi-decade investments.

Contrast this with the period following the 2008 financial crisis. The ensuing economic pain, political polarization, and public discontent led directly to the Budget Control Act and sequestration, which imposed punishing cuts on the defense budget. Allies and adversaries alike watched as Americans debated whether they could afford to modernize an aging nuclear triad. The signal was one of constraint and introspection, raising quiet questions in foreign capitals about the long-term reliability of America’s security guarantees. A nation struggling with internal economic and social crises inevitably projects an image of distraction and dwindling resolve.

Adversaries did not miss this lesson. They astutely integrated America’s domestic vulnerabilities into their national security strategies. China and Russia are engaged in a relentless campaign of information warfare designed to exacerbate our societal fissures. State-controlled media outlets like CGTN (Chinese) and RT (Russian), amplified by armies of bots and trolls on social media, relentlessly spotlight American inequality, racial tensions, and political gridlock.

Their goal is twofold: erode the confidence of Americans in their own democratic system and persuade the world that the United States is a chaotic, declining power whose deterrence is brittle and promises are hollow. By turning societal metrics into weapons against Americans, adversaries aim to achieve strategic gains without firing a shot.

Of course, the relationship between societal health and defense is not without its complexities. A valid counterargument holds that a society enjoying high well-being might become complacent, preferring to spend its “peace dividend” on social programs rather than defense. The post–Cold War era saw this exact debate, as calls to shift funding from “guns to butter” grew louder.

This presents a genuine leadership challenge that requires articulating why investments in national security are essential to protecting the very prosperity and stability Americans enjoy. The choice is not always between a new healthcare program and a new submarine. A strong, healthy, and educated populace, free from economic precarity, is the very foundation that allows a nation to project power and afford the tools of its own defense. A robust social safety net and a powerful military are not mutually exclusive—they are mutually reinforcing pillars of a resilient state.

This calculus extends to the nation’s most critical strategic advantage: America’s network of alliances. The strength of the North Atlantic Treaty Organization (NATO), for instance, is not purely a measure of its combined military hardware. It is rooted in a collective commitment to democratic values and the shared societal well-being of its members.

A stable, prosperous, and unified America reassures allies and strengthens collective deterrence. Conversely, an America seen as internally fractured and unreliable invites doubt, weakening the very alliances that magnify American power. When allied societies are confident in American leadership, collective credibility soars.

Therefore, Americans must rethink national security for the twenty-first century by placing American well-being at the very heart of our strategic imperatives. Bridging the economic divide not only broadens our tax base but also strengthens social cohesion, enabling sustainable defense budgets without overburdening taxpayers. Revitalizing education fuels scientific breakthroughs and cultivates the skilled workforce needed to modernize our nuclear command, control, and delivery systems. Upgrading infrastructure, from critical ports and highways to resilient cybersecurity networks, enhances our logistical agility, accelerates force deployment, and bolsters the credibility of our deterrent. By fostering political unity, we project resolve to allies and adversaries alike, inoculating our society against foreign information warfare and ensuring decisive, coordinated responses in times of crisis.

The defining contest of this century will not be waged on traditional battlefields but in a struggle of systems: our free, prosperous, and cohesive society versus an authoritarian model of centralized control. To secure our peace, we must fortify America’s Silent Shield at home. The credibility of our nuclear deterrent, and, by extension, our global leadership, will always mirror the resilience and unity of the nation it protects.

America’s Silent Shield: How Domestic Strength Sustains Nuclear Power was originally published on Global Security Review.

Since January 20, Trump administration officials have announced an end to US participation in NATO military exercises; floated plans to relinquish NATO’s Supreme Allied Commander post (held by an American since NATO’s founding); proposed withdrawing 10,000 troops from Eastern Europe; threatened the sovereignty of NATO ally Canada; raised the prospect of using force to seize Greenland (a territory of NATO ally Denmark); derided “freeloading” Europeans; said of Vladimir Putin that America “should take him at his word”; torpedoed NATO’s unanimous declaration to “never recognize Russia’s illegal annexations of Ukrainian territory, including Crimea”; and suggested America’s NATO allies would not “come and protect us” in a time of crisis. This follows Trump’s 2024 invitation to Putin’s henchmen to “do whatever the hell they want” to allies failing to meet NATO’s defense-spending requirements; 2018 threat to withdraw from NATO; and a 2016 declaration that he would defend NATO members under attack only if they had “fulfilled their obligations to us.” Add it all up, and Trump’s view of NATO diverges dramatically from that of what was once known as the “Grand Old Party.”

For instance, as he took the reins as NATO’s first military commander, General Dwight Eisenhower—a future Republican president—called NATO “the last remaining chance for the survival of Western civilization.” President Richard Nixon viewed NATO as “a moral force.” President Gerald Ford believed NATO “protected the free world from the threat of aggression.”

President George H. W. Bush called NATO “an insurance policy.” Indeed, for America, NATO insures against the worst scenario: another European conflict triggering another global war. For the rest of NATO, the alliance is a security guarantee backed by the United States. Without that guarantee, there is no security in Europe, as history has a way of reminding those on the outside looking in, from Cold War Hungary to post–Cold War Ukraine.

President George W. Bush called NATO “the essential foundation of transatlantic security.” This essay did not forget President Ronald Reagan. However, many of those who claim Reagan’s mantle forget that he was an unwavering NATO advocate—during and after the Cold War. Rather than dismissing NATO as “obsolete,” Reagan called NATO “the core of America’s foreign policy and of America’s own security.” Rather than alarming NATO allies, Reagan reassured them by echoing the words of the North Atlantic Treaty: “If you are threatened, we’re threatened…. An attack on you is an attack on us.”

Rather than distorting NATO into a transactional protection racket, Reagan championed NATO as a “community of democratic states” and “a bond which has served us so well.”

Reagan never questioned NATO’s relevance, never browbeat NATO laggards, never threatened withdrawing from NATO, and never raised doubts about America’s commitment to NATO. Instead, Reagan championed NATO as “an antidote to chaos,” “a living commitment of the nations of the West to the defense of democracy and individual liberty.”

Importantly, Reagan did not think NATO’s mission was over when the Berlin Wall fell. In fact, he endorsed NATO’s continued growth. “Room must be made in NATO for the democracies of Central and Eastern Europe,” he declared after the Cold War thawed. And even after Moscow began walking the path of reform, Reagan cautioned, “We cannot afford to forget that we are dealing with a political system, a political culture and a political history going back many decades, even centuries…. We must stick with the strategy of strength.” In short, Reagan shrewdly saw NATO as a hedge against a Russia that might revert to revanchism—which is exactly what has happened.

Putin’s Russia violated nuclear treaties, conventional-weapons treaties, and its own pledge to “respect the independence…sovereignty and existing borders of Ukraine”; warned NATO member Poland that its western territories were “a gift from Stalin”; dismembered NATO aspirants Georgia and Ukraine; countenanced and/or conducted cyberattacks against American energy infrastructure; interfered in elections throughout NATO’s membership roster; conducted sabotage operations across NATO’s footprint (including American targets); threatened use of nuclear weapons; aided and funded attacks against American forces; provided targeting data to support Houthi attacks against allied ships; and made “massive investments in its defense sector” (according to Trump’s own intelligence officials). In light of all of that—and the Kremlin’s long history of deceit—Reagan would never “take Putin at his word.”

GOP presidents, and their democrat counterparts, supported NATO because they recognized that NATO serves America’s interests. For 40 years, NATO helped deter Moscow and prevent the Cold War from turning hot. But that is just a fraction of how NATO has served America’s interests.

Thirteen current NATO allies deployed troops to assist America in defending South Korea. NATO militaries, infrastructure, and decades of interoperability served as the nucleus for the coalition that ejected Iraq from Kuwait, with NATO allies deploying thousands of troops to assist America.

The only time NATO’s all-for-one collective-defense clause was invoked was after September 11, 2001, when NATO allies rushed aircraft and personnel to this side of the Atlantic to guard America’s skies. NATO then bled with America in the Sisyphean campaign that followed, with 455 Brits, 158 Canadians, 86 French, 54 Germans, 48 Italians, 43 Danes, and 40 Poles dying in Afghanistan. When America withdrew from Afghanistan—20 years after the attacks on America’s capital, America’s military headquarters, America’s largest city—74 percent of the foreign troops deployed in the country that spawned 9/11 were not Americans. The vast majority were NATO allies. Trump is apparently unaware of this history.

In Operation Iraqi Freedom, 16 NATO allies sent troops when America asked for help. Hundreds of NATO troops—Brits, Italians, Poles, Bulgarians, Latvians, Danes, Dutch, Romanians, Hungarians, Czechs—died in Iraq, as did 18 soldiers from Ukraine, a country that is not a NATO ally but certainly acts like one.

In the post Iraqi freedom years, seven NATO members conducted airstrikes against the ISIS caliphate. Again, NATO was there.

Far from “freeloading,” NATO allies Britain, Canada, France, Italy, the Netherlands, Norway, and Spain are supporting operations in the Red Sea. Likewise, British, French, Italian, Spanish, and Canadian assets are promoting freedom of navigation in the Indo-Pacific.

European nations sent more aid to Ukraine than the US. Britain and France are organizing a peacekeeping force for postwar Ukraine.

NATO has eight battlegroups defending its most at-risk members along the eastern flank. Only one is American-led.

Britain leads the battlegroup in Estonia, supported by Denmark, France, and Iceland. Britain is committing resources to defend NATO’s northern flank. And the aircraft carrier HMS Prince of Wales just commenced a globe-spanning mission—the largest deployment of British naval airpower in a quarter-century.

Germany leads the battlegroup in Lithuania, backed by Belgium, Czechia, Iceland, Luxembourg, the Netherlands, and Norway. Germany is building permanent bases in Lithuania for 4,800 German troops. Germany is spearheading a continentwide missile shield. And Germany’s parliament recently approved a massive defense-infrastructure fund.

Canada leads the battlegroup in Latvia, supported by 10 other NATO allies. France leads NATO’s battlegroup in Romania. Pouring almost 5 percent of GDP into defense, Poland fields NATO’s third-largest military. Sweden is quadrupling production of anti-tank weapons.

What NATO is doing and deterring underscores something General James Mattis observed almost a decade ago, “If we did not have NATO today, we would need to create it.”

This begs the questions: what if we did not have NATO? What if these first hundred days mark the last days of history’s greatest alliance for peace?

NATO is designed not to wage war, but to deter war. If there is any doubt about NATO’s collective-defense guarantee—and these first hundred days have created enormous doubts—Putin could be tempted to do in the Baltics what he has done in Ukraine. That would force NATO to blink or fire back. And that would lead to terrible outcomes. The former means the collapse of NATO—and with it, the entire US-led alliance system. The latter means great power war.

The best way to prevent such dire outcomes is through deterrent military strength, clarity of intent, and certainty of cause and effect. Trump’s words and actions have undermined all of these.

What the transactional Trump administration fails to recognize is that by undermining NATO, it is undermining America’s security. If a cyberattack or EMP blast or bioweapon paralyzes America; if ISIS or al Qaeda or some other terror group unleashes something worse than 9/11 or 10/7; if Moscow blinds America’s constellation of satellites; if Beijing moves against Taiwan; or if Pyongyang restarts the long-paused Korean War, America will call for help.

A post-NATO Europe may be unable or unwilling to answer.

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.
