The Cuban Missile Crisis

Canyon begins her article by employing the Cuban Missile Crisis as an example of where diplomacy rather than military force carried the day. Her explanation is simple disinformation and misunderstands how nuclear deterrence works.

Early in the crisis, President John F. Kennedy moved nuclear-armed bombers to Air Force bases in Florida, lining them up wing tip to wing tip, as a visible display of the nuclear hell both Cuba and the Soviet Union would face if Nikita Khruschev did not remove nuclear weapons from Cuba. That signal was seen by the Soviets.

President Kennedy also called the then-recent deployment of Minuteman I intercontinental ballistic missiles (ICBM) his “ace in the hole.” He credited his ICBMs with forcing the Soviets to back down. Minuteman I was very much American escalation dominance that the Soviets could not match.

He also implemented a blockade around Cuba. When the Soviet submarine B-59 attempted to run the blockade, the USS Beale depth charged the submarine. Rather than launching its nuclear torpedoes against the Beale, B-59 retreated.

Contrary to Canyon’s assertion that diplomacy carried the day, it was military strength and nuclear superiority that carried the day. General Secretary Khruschev knew that the United States had a superior nuclear arsenal and backed down.

Arms Racing

Canyon is also concerned that the United States will invite an arms race should it develop the full spectrum of capabilities that are required to effectively deter China, North Korea, and Russia. The reality is the race has already begun. The only participant that is yet to leave the starting block is the United States.

Russian strategic nuclear modernization is nearly complete, with Russia also maintaining at least a 10 to 1 advantage in theater nuclear weapons. China is adding at least 100 new nuclear weapons per year and will soon outmatch the United States.

North Korea is now capable of striking the homeland with intercontinental ballistic missiles. According to Kim Jung Un, North Korea will build an arsenal of 500 nuclear weapons.

It is only the United States that is yet to field a new nuclear delivery system. The newest American nuclear delivery vehicle, the B2 bomber, is three decades old.

Contrary to the aspirations of nuclear disarmament advocates in the United States, not a single nuclear-armed adversary is willing to follow the United States down the path of disarmament. The post–Cold War era, three decades now, is a glaring example of the failures of the disarmament delusion.

Canyon is completely wrong when she asserts that China and Russia are modernizing and expanding their nuclear arsenals because of American nuclear modernization. They began their own nuclear modernization and expansion efforts long before the United States began its effort to replace aging weapons with new variants.

It was not American nuclear weapons that drove Chinese and Russian modernization to begin with. It is American superiority in conventional precision-guided weapons, which neither adversary can match, that led them to follow a strategy like President Dwight Eisenhower’s New Look Policy.

For some reason, Canyon claims that the ability to maintain nuclear escalation dominance is advocating “unchecked militarization.” Nothing could be further from the truth. Nuclear forces are a deterrent to conventional military aggression. Historically, great powers wage war four to six times per century, killing millions in the process. Nuclear weapons put an end to great power war and led to a more than 90 percent decline in conflict-related casualties. Lest Canyon forget, the last great power war, World War II, led to the death of 70 million people and saw the United States spend almost half of its gross domestic product fighting the war.

Canyon, like many in the disarmament community, mistakenly believes that weakness leads to peace. They incorrectly impose their own aversion to conflict onto Xi Jinping, Vladimir Putin, and Kim Jung Un. In reality, these authoritarians, who are actively seeking to topple the American-led international order, only see American passivity as weakness and an opportunity to coerce the United States.

Peace through strength is no mere slogan. It is the most accurate and effective way to deter America’s adversaries and ensure they never believe that they can achieve their objectives through conflict.

Defense Spending

Canyon also argues that defense spending is too high and the need to modernize all three legs of the nuclear triad is wasteful. Instead, she proposes increasing spending on social programs. Any examination of federal, state, and local budgets illustrates that Canyon is again incorrect.

In 2024, the federal budget was $6.75 trillion. Of this, $841.4 billion, 14 percent, went to defense spending. Of defense spending, about $50 billion was dedicated to current operation and modernization. This was about 6 percent of defense spending and less than 0.1 percent of federal spending.

Federal, state, and local governments spent more than $10 trillion in 2024. The federal government alone spent 69 percent of its budget on social programs. That is approximately $4.6 trillion—more than all federal revenue collected ($4.4 trillion) in 2024. Excluding federal pass-through funds, state and local governments spent an additional $4 trillion in 2024. State and local governments spent 65 percent of their budgets on social programs—another $2.6 trillion. Federal, state, and local governments spent $1.8 trillion just on anti-poverty programs—more than twice the defense budget.

According to the Centers for Medicare and Medicaid Services, the federal agency that runs these two programs, Medicare and Medicaid lose more than $100 billion every year to waste, fraud, and abuse. That is twice the cost of the entire nuclear enterprise. Surprisingly, Canyon is not bothered by this and other waste, fraud, and abuse in federal, state, and local programs. They are affordable. In her mind, it is nuclear spending that is breaking the bank.

The simple fact is that social justice warriors have never seen a dollar they do not want to spend. After all, more than 100 percent of federal revenues are already spent on their preferred programs. State and local governments spend two-thirds of their budgets on social programs. Americans also spend more than $450 billion a year in charitable donations. Despite the spending on social programs, the demand only grows.

Defense spending, however, is at a 70-year low. At 3.4 percent of gross domestic product, these rates of defense spending have not been seen since prior to World War II.

Thus, when Canyon argues that too much is spent on defense and nuclear modernization, she is flat wrong. It is just the opposite.

Americans now live in a nation where social programs crowd out defense spending at a time when avoiding war is only possible by fielding a military and a nuclear force that is powerful enough to not only deter Russian aggression, but Chinese, North Korean, and Iranian as well. That can never be done by good intentions. Weakness is provocative. Peace comes through strength and an unwillingness by aggressive adversaries to challenge the United States.

Canyon is wrong in her reading of history, wrong in her understanding of strategy, and wrong about government spending. The time is now to have a guns-versus-butter debate because it may soon be too late.

Escalation Dominance Does Matter was originally published on Global Security Review.

Specifically, if the United States does not reduce government spending and reduce the national debt, the nation’s ability to modernize the nuclear arsenal and keep pace with rapid technological advancements is not possible. It is time for a “guns versus butter” debate that ultimately reigns in domestic spending.

The relationship between economic power and military strength is well-documented. As Paul Poast notes, “Money is power.” Paul Kennedy’s research empirically shows, from the Roman Empire to the Cold War, that economic decline often precedes the erosion of military dominance. In today’s context, the United States faces a growing national debt, projected to surpass $50 trillion by 2033, according to the Congressional Budget Office. While this staggering figure is often discussed in terms of domestic economic consequences, such as inflation and interest rates, its implications for national security are equally alarming. The costs of servicing this debt, combined with rising entitlement spending, will leave fewer resources available for defense.

Deterrence and the Need for Modernization

Deterrence, particularly nuclear deterrence, is the bedrock of American security strategy since the end of World War II. The ability to deter adversaries—whether through nuclear capabilities or advanced conventional forces—depends on maintaining a credible threat of retaliation. This requires not only a robust military infrastructure but also a commitment to modernization.

The American nuclear arsenal, a cornerstone of deterrence, is aging. The nuclear triad—comprising land-based intercontinental ballistic missiles (ICBM), ballistic missile submarines, and strategic bombers—was largely developed during the Cold War. Many of these systems are nearing the end of their operational lives, and without significant investment, they will soon become less effective. The Sentinel ICBM program and the Columbia-class submarine are critical components of this modernization effort, but they come with hefty price tags. The Department of Defense estimates that modernizing the nuclear triad will cost over $1.5 trillion over the next 30 years.

This modernization is not optional. As adversaries like China and Russia expand their nuclear capabilities, failure to update our arsenal would undermine the credibility of American deterrence. In addition, North Korea’s continued nuclear development and Iran’s pursuit of nuclear weapons only increase the need for a reliable deterrent. However, modernization is only possible with sustained investment. If the US continues its current fiscal trajectory, defense spending will only decline, as it already has, by the growing demands of interest payments on the national debt and mandatory spending on programs like Social Security and Medicare.

Technological Advancements: The New Frontier of Deterrence

Beyond nuclear modernization, the future of deterrence will be defined by emerging technologies. As Michael Horowitz notes in his 2020 article, artificial intelligence (AI), quantum computing, autonomous drone warfare, cyber warfare, and hypersonic weapons are reshaping the nature of conflict. These technologies have the potential to transform military operations by providing advanced capabilities for precision strikes, autonomous systems, and cyber operations that can incapacitate an adversary’s critical infrastructure without the need for traditional warfare.

However, the integration of these technologies into the American defense apparatus requires substantial investment in research, development, and deployment. China is already making significant strides in AI and quantum technologies, while Russia continues to prioritize hypersonic weapons development. The US cannot afford to fall behind in this technology race, as the consequences for deterrence are dire. A nation that lacks cutting-edge capabilities risks becoming vulnerable to both traditional and non-traditional forms of warfare.

Yet, technological innovation is expensive. Maintaining a competitive edge in AI, cyber capabilities, and other advanced technologies requires not only a well-funded military but also a robust industrial and academic infrastructure. If government spending continues to spiral out of control, the funds necessary to develop and integrate these technologies will be diverted to service the national debt or shore up social welfare programs. This creates a vicious cycle in which the American military falls further behind while adversaries close the gap—or even surpass the United States—in critical areas.

The Economic Roots of Military Power

The decline in military readiness that results from unchecked government spending and rising debt is not hypothetical. Historical examples illustrate the dangers of economic mismanagement leading to military weakness. The Soviet Union, for instance, collapsed, in part, because it overextended itself militarily while failing to manage its economic challenges. While the US is far from Soviet-style economic collapse, the lesson is clear; no nation can maintain military dominance without a strong economic foundation.

Paul Poast, a leading scholar on the political economy of security, highlights the importance of economic capacity in sustaining military power. Military expenditures are only sustainable if the state has the economic resources to support them. Poast argues that focusing solely on military budgets without addressing the underlying economic conditions that make those budgets possible is a recipe for disaster.

In the American case, the growing national debt is directly threatening the economic foundation necessary for sustained military investment. Interest payments on the debt already consume $900 billion each year, and that figure is expected to rise significantly in the coming decade. As interest rates increase, so will the cost of servicing the debt, leaving fewer funds available for national defense. Without a course correction, this fiscal irresponsibility will leave the US incapable of maintaining its military superiority, much less modernizing its forces for the future.

The Path Forward: Fiscal Responsibility as a National Security Imperative

To avoid this grim future, the US must prioritize fiscal responsibility as part of its broader national security strategy. There are no historical examples of any nation borrowing its way to prosperity. This begins with reining in government spending and reducing the national debt. While this may require difficult political choices—such as reforming entitlement programs or scaling back certain discretionary spending—the alternative is far worse. A nation that cannot afford to invest in its defense is a nation that cannot defend itself.

Moreover, reducing the national debt would free up resources for the investments necessary to modernize the nuclear arsenal and integrate emerging technologies into the military. By putting the nation’s fiscal house in order, it is possible to ensure that the US remains a global leader in both traditional and technological forms of deterrence. Failure to do so risks not only economic consequences but also the erosion of America’s ability to defend its interests and allies in an increasingly volatile world.

The political economy of security is not just about guns and bombs—it is about dollars and cents. If the nation fails to address the growing national debt, the US will prove unable to modernize its nuclear arsenal or keep pace with the technological change that is defining the future of warfare. Fiscal responsibility is not just a domestic issue; it is a national security imperative. Only by controlling spending and reducing debt can deterrence remain credible.

By taking the necessary steps now, the nation can secure a future where America’s deterrent capabilities remain strong and its security unassailable. Failing risks a future where deterrence fails, and with it, the ability to protect the nation and its allies. The stakes could not be higher.
