On December 23, 2025, the Pentagon released its annual 2025 China Military Power Report to Congress—a reminder that America is still trying to deter tomorrow with yesterday’s force. The report assesses China’s stockpile stayed in the low 600s through 2024 but remains on track to have over 1,000 nuclear warheads by 2030, while Russia continues to brandish tactical (non-strategic) nuclear weapons to shield conventional aggression. Yet U.S. deterrence planning still assumes that sufficiency against one peer will scale to two.

Within the bomber community, personnel are trained to operate and make decisions amid uncertainty. Deterrence cannot rely on idealized scenarios. Washington, however, continues to plan and budget as if deterring one peer at a time is adequate to maintain peace. Since the Nixon administration elevated “strategic sufficiency,” the U.S. has preferred a survivable second-strike posture over matching adversary numbers, even as U.S. Strategic Command (STRATCOM) Commander Adm. Charles Richard testified in 2020, “We do not seek parity.”

That posture of sufficiency made sense when the U.S. faced one major nuclear superpower at a time. It makes less sense when the U.S. must deter two nuclear peers, potentially in overlapping crises while also accounting for a third in North Korea. The 2023 Congressional Commission on the Strategic Posture of the United States warned the nation is “ill-prepared” for a future where China and Russia can coordinate, or opportunistically exploit dual crises.

The issue is not that U.S. modernization appears timid on paper. Instead, it is optimized for a single adversary. A survivable second strike against one major nuclear opponent is not enough as a credible deterrent against two, especially if one adversary believes the other will absorb U.S. attention. Deterrence developed for one enemy breaks down when facing multiple opponents.

Modernization is also colliding with the same budget dysfunction that has battered conventional readiness for years. Continuing resolutions and shutdown threats do not just delay programs; they advertise doubt about U.S. resolve. In deterrence, doubt about political will can be just as harmful as uncertainty about capability.

Enter the logic of reciprocity. The White House’s February 2025 memorandum on Reciprocal Trade and Tariffs argues that reciprocal measures are not punishment; they are a way to restore balance when competitors exploit unequal terms. Reciprocity is a framework for fairness, and fairness is what makes commitments believable.

Deterrence needs a similar framework. Strategic fairness demands a posture calibrated to the combined capabilities of the adversaries the U.S. must deter, not an accounting trick that treats them sequentially. Dynamic Parity offers that calibration: match the aggregate nuclear threat, go no further, and use that ceiling to avoid both arms racing and strategic vulnerability.

Dynamic Parity is “parity without superiority.” It rebuffs a race for numerical dominance, but it also rejects minimalist postures that assume an adversary will politely wait its turn. It restores equilibrium as the foundation of deterrence in a multipolar era.

Skeptics argue that “parity” invites an arms race or abandons arms control. Dynamic Parity does the opposite: it clearly separates what is required from what is excess, with the numerical arsenals determined by the adversary and then matched by America. This establishes a disciplined standard for force planning. That discipline also enhances the U.S. position in future risk-reduction negotiations by making the baseline requirements explicit instead of improvised during a crisis.

Strategy, however, is not self-executing. If Dynamic Parity is the strategic logic, Congress needs a budgeting structure that can deliver it. The National Sea-Based Deterrence Fund provided the Columbia-class ballistic missile submarine program with authorities that support long-lead procurement and multiyear contracting.

Congress should implement that approach throughout the nuclear enterprise via a National Strategic Deterrence Fund. The goal is not to escape oversight; it is to safeguard the core of deterrence from annual budget brinkmanship and start-stop inefficiency. If the fund is protected as non-discretionary spending with multiyear authority, modernization timelines become actual plans rather than mere hopes.

Here is what that would look like in practice:

• Direct the next Nuclear Posture Review to adopt a concurrency standard and use Dynamic Parity as the force-planning logic.
• Create a National Strategic Deterrence Fund with multi-year and long-lead authorities across delivery systems, warheads, infrastructure, and nuclear command, control, and communications.
• Require annual execution reporting, i.e., schedule, industrial capacity, and funding stability, so Congress can measure delivery and not intent.

This is about credibility, not bookkeeping. The State Department’s International Security Advisory Board warned in 2023 that extended deterrence hinges on the perception of sustained capability and resolve. Allies and adversaries do not parse budget documents; they watch whether the U.S. executes what it promises.

Execution is the signal. Russia’s 2024 Fundamentals of Nuclear Deterrence establishes clear redlines for potential nuclear use while deliberately preserving threshold ambiguity. China is building the force structure for nuclear coercion alongside conventional power projection. If Washington cannot modernize on schedule and at scale, because budgets lurch from continuing resolution to shutdown threat, adversaries will read that as strategic hesitation, not fiscal noise.

Reciprocity works only when it is enforced. In nuclear deterrence, enforcement means a posture designed for concurrency and a budget mechanism that delivers it. Dynamic Parity provides the standard; a National Strategic Deterrence Fund provides the spine. In a multipolar nuclear world, balance against combined nuclear threats is not a theory, it is the price of credibility.

Reciprocity in Deterrence, Not Just Trade was originally published on Global Security Review.

As a strategy, MAD was considered but jettisoned by the United States 65 years ago. For example, President John F. Kennedy noted, “Above all, while defending our own vital interests, nuclear powers must avert those confrontations which bring an adversary to a choice of either a humiliating retreat or a nuclear war. To adopt that kind of course in the nuclear age would be evidence only of the bankruptcy of our policy, or of a collective death-wish for the world.” Kennedy succeeded in adopting a strategy short of all-out retaliation that came to be known as “flexible response,” which, in 1974, was fully developed by James Schlesinger and eventually codified in Presidential Defense Directive 59.

Whether the United States has 10,000 or 1,500 strategic nuclear weapons, American forces were designed to have a secure retaliatory capability at any level of conflict. The objective was to end any conflict as soon as possible and at the lowest level of destruction. The American objective was not to burn an adversary’s cities to the ground. American deterrence strategy was to hold at risk what the adversary valued most.

Critics of current deterrence strategy assume that no nuclear-armed adversary of the United States believes in “fighting” a nuclear war. So, the US should drop its long-held deterrence strategy and go back to MAD or something like it. At the same time, many of these critics join nuclear abolitionists to support nuclear weapons but only to deter, not engage, in warfighting. If conflict breaks out and these weapons will not be used in retaliation, then nuclear forces are off the table and reduced to a bluff.

The mistaken notion that the US has a MAD strategy plays into the hands of Russia and China. These two nations both seek to escalate or threaten to escalate in a crisis or conflict with the limited use of nuclear weapons. The objective is to get the United States to stand down and not come to the defense of her allies, a restraint to give Russia and China a strategic advantage.

Unfortunately, much of the current commentary on nuclear threats still assumes the US and its adversaries maintain a mutually assured destruction strategy as the best means to avoid any use of nuclear weapons. Annie Jacobson’s recent book, On Nuclear War: A Scenario, describes a mutually assured destruction strategy, which she assumes the US maintains, as simply MAD or crazy. She posits that any initial use of nuclear weapons would almost automatically result in the all-out use of such weapons, leading to nuclear winter and killing billions. As such, she calls for the entirety of American nuclear deterrence to be jettisoned.

Being in the deterrence business, it is important for Congress, the media, the executive decisionmakers in the military and Department of Defense to fully understand what deterrence, as practiced by the United States, entails and why it must be sustained.

To explain this requires a review of history and an understanding that adversaries of the United States and the West sought military advantage through enhanced nuclear weapons technology. Over time the challenge for the US to sustain deterrence changed. The Soviets sought to put nuclear weapons in space, then built a huge first-strike missile force, then deployed thousands of medium-range SS-20s to intimidate and split NATO, and, most recently, built a theater-strike capability to keep the United States and NATO from winning the war in Ukraine.

The US nuclear deterrent was never one size fits all and automatically fit for purpose. For example, the US and NATO faced a huge conventional military threat from the Soviet Union from the beginning of the Cold War on the plains of central Europe, a place called the Fulda Gap. The Soviet and Warsaw Pact tanks were not matched by American conventional forces. President Dwight D. Eisenhower did not wish to bankrupt the US treasury by building such a large and costly conventional military. The available alternative was to establish a nuclear umbrella over Europe, primarily aimed at Soviet tank armies. Thus, in the initial Cold War period, the US assumed a nuclear conflict would most probably grow out of an initial conventional war.

As technology improved, however, a threat emerged that could markedly change the correlation of forces between the United States and the USSR. The US still sought to deter a potential Soviet push into central Europe, but an additional threat was a potential Soviet pre-emptive first strike seeking to eliminate much of the American extended deterrent, followed up by a subsequent conventional invasion of Europe.

In 1963, the American strategic nuclear deterrent consisted of 6,000 nuclear warheads while the Russians had 600 warheads. As President Kennedy remarked, this strength, and particularly the newly deployed Minuteman missiles, were “my ace in the hole” that gave the United States the strategic advantage that peacefully ended the Cuban Missile Crisis.

However, by the time the next decade ended, the 1972 Strategic Arms Limitation Talks (SALT) “arms control” treaty process was implemented and the USSR largely caught up, deploying 7,800 warheads compared to the US force of 8,700 warheads. Most worrisome was the new Soviet land-based missile force of 3,000 warheads on highly accurate SS-18s—with the overall Soviet nuclear force projected to grow to over 24,000 warheads by 1993.

As Secretary of Defense Melvin Laird told Congress in 1974, “the Soviets are going for a first strike force and there is no doubt about it.” The SS-18 eventually held at risk the entirety of the US land-based intercontinental ballistic missile (ICBM) force. This was the only American deterrent force that was sufficiently accurate to target key Soviet leadership and military targets without requiring “city busting.”

The US stopped deploying land-based missiles at 1,050 and associated warheads at around 2,000—assuming the USSR would show equal restraint. But Moscow built a huge land-based ICBM force that could take out the nation’s Minuteman missiles, leaving the US without the ability to hold key Soviet assets at risk. This perceived imbalance was known as the “window of vulnerability” where the US faced the prospects of a Soviet-initiated first strike that would leave US leaders exactly where President Kennedy worried it would.

The US solved the strategic equation of the window of vulnerability, the Soviet empire collapsed, the US added the Trident II D-5 submarine-launched ballistic missile and Peacekeeper land-based ICBM, Soviet SS-20s were banned, and the Strategic Arms Reduction Treaty (START) arms control process brought Russian warheads down to under 2,000.

In April 1999, Russian President Boris Yeltsin, economically unable to rebuild a Soviet-era nuclear force, decreed that Moscow develop highly accurate, small, low-yield, battlefield nuclear weapons, which his successor, Vladimir Putin, did in earnest. As former Vice Chairman of the Joint Chiefs of Staff General John Hyten warned, these theater nuclear weapons were designed to “escalate to win” a conventional conflict or crisis between Moscow and Washington.

Putin thinks the US will not respond to the small-scale use of nuclear weapons because the US will not want to risk escalation and the possibility of strategic nuclear exchange. That is why Putin made exactly these threats over NATO’s intervention in the war against Ukraine.

Both Russia and China assume the relative weak theater nuclear forces the US maintains are now insufficient to match escalatory threats from Moscow and possibly Beijing. This point was emphasized by the 2023 Strategic Posture Commission report in laying out the opening of a new window of vulnerability.

The US is indeed now developing a greater theater nuclear deterrent to close the technology gap. However, simply adding to America’s conventional deterrent is not sufficient. As military leadership has repeatedly emphasized, if adversarial nuclear forces are introduced into a conventional conflict, the American advantage ceases. In short, conventional military leverage disappears.

The central tenets of mutually assured destruction no longer apply. MAD was jettisoned long ago. More importantly, America’s adversaries employ credible threats with the nuclear forces. New technology and expanding adversary arsenals are undermining the limited deterrent value of the American nuclear arsenal, a fact that must change if the United States seeks to ensure it does not find itself embroiled in a conflict where capitulation or Armageddon are the nation’s only options.

Current challenges include the disparity in nuclear capabilities, with Russia’s projected 7,500 warheads and China’s rapid buildup to 3,500 by 2035. The U.S. TRIAD faces maintenance issues, necessitating immediate investments in updated systems to avoid strategic vulnerabilities. Recommendations highlight the need to accelerate programs like the Navy’s nuclear-armed cruise missile initiative, expand the B-21 bomber fleet, and consider additional Columbia-class submarines. These steps are presented as crucial to addressing the growing threats from adversaries while ensuring strategic balance.

The report underscores the urgency of modernizing the U.S. nuclear deterrent to sustain global power and uphold international credibility. Strategic insights from leaders like General McMaster and Secretary Frank Kendall advocate for overcoming budgetary constraints and reinforcing the defense industrial base. The document also highlights broader geopolitical concerns, such as the implications of Russia’s invasion of Ukraine and Iran’s nuclear ambitions, framing modernization as a central pillar of U.S. security policy.

Wild Blue Yonder, By Lt Col Shawn Littleton

With the movie Oppenheimer bringing the Bomb back into our casual conversations, it is a good time to rethink how you feel about the Bomb. Its abstract but existential implications are especially present today as a driver of both conversation and human behavior in an unprecedented way. Will the unleashing of nuclear weapons be the sadly predictable end of mankind that our worst nightmares portend, or will the Bomb fulfill our greatest hopes and be a deterrent backstop that prevents a third World War and enables a global reconciliation that leads to total disarmament? Should we hate or love the Bomb, or somewhere in between?
