Most the world’s approximately 12,100 nuclear weapons are held by just a handful of major world powers. The U.S. and Russia hold nearly 87 percent of the world’s nuclear weapons, with Russia possessing approximately 5,500 and the US holding approximately 5,177, declared  weapons, many of which remain in a state of high alert. China possesses an estimated 600 operational nuclear weapons, with the number having grown by over 100 in recent years. France is estimated to have 290 warheads; the UK, 225; India, 180; and Pakistan, 170. These countries have all maintained stable stockpiles through modernization efforts. However, North Korea maintains an estimated 50 nuclear weapons, but is aggressively developing its nuclear delivery capabilities, including the development of solid-fueled ICBMs and nuclear-capable submarines with Russian backing.

These developments present the growth in nuclear arsenals and nuclear technology, rather than a reduction. The growth includes the qualitative development of nuclear delivery technology, such as hypersonic vehicles and Multiple Independently Targetable Reentry Vehicles (MIRVs), which has undermined the existing balance in the arms race established because of the Cold War.

The New Strategic Arms Reduction Treaty (New Start), which remains the last bilateral US-Russian nuclear weapons agreement, is scheduled to expire on February 5, 2026, without any proposed replacements because of disagreement on the treaty’s terms. In 2023, Russia withdrew from the inspection and data sharing provisions in relation to Ukraine, but the two countries have openly stated to voluntarily meet their respective limit requirements under the treaty since then. If the treaty is allowed to lapse, it is anticipated that each side could begin to increase their nuclear weapons arsenal, which could prompt other nuclear-capable states, including China, to do likewise.

Additionally, the upcoming review conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) set to occur in New York in April 2026, presents additional challenges. Past NPT review conferences have been unable to reach a consensus primarily because of the anger expressed by non-nuclear states toward nuclear-armed states for failing to meet their obligations under Article VI of the treaty to pursue disarmament. As a result of this failure, several treaties relating to the regulation of nuclear weapons, including the Comprehensive Test Ban Treaty (CTBT) have been signed but not ratified by key signatory states and therefore lack the needed verification mechanisms.

Iran may also be motivated to obtain nuclear weapons for the purpose of providing a deterrent against Israel’s expanding conventional and nuclear capabilities. Iran’s nuclear weapons program is one of the most pressing issues confronting the United States and Israel today. Iran is now stockpiling uranium-enriched to 60% levels that are close to the level of enrichment required to produce nuclear weapons. It is also developing new centrifuges at its underground facility, known as Fordow, and is shortening the time it takes to produce a nuclear weapon despite continuing economic sanctions and airstrikes against its military assets.

Further, North Korea indicated that 2025 would be a “crucial year” for its nuclear weapons development program and announced that it successfully tested its Hwasong-20 Intercontinental Ballistic Missile (ICBM) and has increased the size of its nuclear facility at Yongbyon; it intends to complete construction of missile factories by 2026. Regional conflicts on the Korean Peninsula and in the Middle East, especially those involving Iran and Israel continue to pose a substantial risk of unintended escalation in the increasingly complex and multi-polar world we live in today.

Disarmament is nothing more than a relic of a bygone era. Nuclear-armed states are engaging in modernization efforts and the language used by these states appears to lower the threshold for using these weapons, seen from Russia’s nuclear threats regarding Ukraine to the lowering of nuclear alert status. Verification is touted by some as much as possible through the International Atomic Energy Agency (IAEA); however, the nuclear powers are unwilling to provide the level of transparency needed to verify compliance with any proposed disarmament treaty. Furthermore, although non-proliferation efforts have successfully limited the number of new nuclear weapons being developed, until nuclear-armed states reduce their own arsenals, non-proliferation efforts will remain a hollow pillar.

In 2026, nuclear arsenals among the great powers are expected to continue expanding. At the same time, the expiration of New START is likely to lead to the failure of the NPT Review Conference, further weakening the Nuclear Non-Proliferation Treaty regime. These challenges will be compounded by the emergence of modern technologies, including artificial-intelligence–enabled command systems and hypersonic delivery vehicles, which increasingly blur the line between conventional and nuclear capabilities. When combined with the proliferation activities of states such as Iran and North Korea, these developments will place unprecedented strain on diplomatic efforts to prevent conflict and miscalculation. This risk is heightened further by escalating tensions among the world’s major powers.

The Dawn of 2026 and Challenges to Non-Proliferation was originally published on Global Security Review.

After World War II, both Japan and Germany became allies of the United States while the Soviet Union became a serious enemy. Most importantly, the Soviet Union established in Eastern Europe an alliance of nations under the Warsaw Pact. Thus, a decades-long Cold War began.

It was widely assumed that the collapse of the Soviet Union heralded an era of global cooperation and the end of great power competition and conflict. Arms control brought about the Intermediate Nuclear Forces Treaty (INF), Strategic Arms Reduction Treaty (START I and II) and the Conventional Forces in Europe Treaty (CFE) agreements.

Today, however, as many military and diplomatic experts conclude, the dangers facing the United States and its allies are more complex and more serious than perhaps at any time since the end of WWII. Now, more than ever, arms control remains elusive.

Nuclear conflicts are now among the most serious potential dangers, including proliferation of nuclear weapons, the pending end to formal strategic arms limits, and the actual use of theater nuclear force arising out of existing conventional conflicts.

To lessen such dangers, nuclear abolitionists proffer numerous arms control proposals. Six ideas are most common: (1) a policy of no first use of nuclear weapons; (2) adoption of a “minimum deterrent” nuclear strategy; (3) the elimination of intercontinental ballistic missiles (ICBMs); (4) a unilateral freeze of US nuclear force development; (5) an extension of New START nuclear arms limits; and (6) abandonment of any new theater nuclear forces such as the nuclear sea-launched cruise missile (SLCM-N) or the sea-launched cruise missile. All of these strategies harm American and allied security and make worse the strategic nuclear balance.

The US extended deterrent has, for 70 years, rested on the option of using nuclear force to stop massive conventional attacks on US forces and allies overseas. Depending on the regional military balance, such nuclear extended deterrent options were, and remain, viewed by our allies as central to keeping their nation safe from Soviet/Russian and Chinese aggression.

Minimum deterrence strategies assume the only retaliatory targets the US needs to hold at risk are adversary cities where a few hundred nuclear warheads are all that is needed to deter. This doctrine assumes Russia and China will be completely deterred by the fear of losing large numbers of their civilian population. But this ignores the fact that these regimes murdered millions of their own people to gain power—showing little value for human life. Even worse, a minimum deterrence strategy would also leave alive the leaders of such nations as well as their nuclear and conventional forces with which they will commit aggression.

Cutting out the land-based ICBM force and a third of the ballistic missile submarine force would unilaterally reduce the US strategic nuclear force to around 500 at-sea on-alert warheads. This would be only a third of the allowed New START treaty force and give an 8 to 1 to 18 to 1 Russian and Chinese advantage in nuclear weapons, respectively. This would ensure that both nations frequently use nuclear weapons for coercion and blackmail.

A freeze on American nuclear force development would be a deterrence disaster. The US has not yet fielded any portion of the modernized triad, which is not rusting into obsolescence. Russia has completed over 90 percent of its own modernization and China is well on its way to tripling the size of its nuclear force over the next decade. Neither would participate in a unilateral freeze. Again, the United States would face a far superior adversary.

An extension of New START sounds attractive but would be harmful to American interests. It would delay any needed uploading of American warheads. It would not affect or make transparent China’s breathtaking nuclear build-up. And without a sea change in Russian behavior, verifying current arms limits would still be impossible, given the past five years of treaty violations by Moscow.

The Congressional Strategic Posture Commission report of October 2023 emphasized the urgency of rebalancing the current gap in US regional nuclear forces. The SLCM-N and better theater air deterrence were key recommended upgrades, both of which would be eliminated by a number of these proposals. It is precisely this deterrence gap which Moscow has leveraged to limit US and allied assistance to Ukraine.

The restraint these arms control ideas wish upon the US military assumes that Russia and China will reciprocate. But in the multiple decades after the end of the Soviet Union, massive US restraint was eventually met with what Admiral Richard has described as a “breathtaking” Chinese build-up and a near matching Russian modernization. As former Secretary of Defense Harold Brown once warned, “We build, they build. We stop; they build.”

Now is the time to reject nuclear abolition for what it is, a purposeful effort to weaken the United States. American lives and freedom depend on it.

Making Nuclear Blackmail Great Again was originally published on Global Security Review.

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.

ICBM EAR Report 13 Jan 2025 was originally published on Global Security Review.

During the webinar, Lowther briefly touched on the alternative and numerically weaker concept of sizing America’s nuclear triad based upon “strategic sufficiency.” This approach would mean deploying just enough nuclear warheads to launch a counterforce first strike on the deployed nuclear delivery platforms of America’s adversaries. For example, it may be possible to strike eight nuclear-capable bombers, which carry 12 nuclear weapons each, with one intercontinental ballistic missile. Thus, the ratio, in this case, would be one American nuclear weapon for 96 (8×12) adversary nuclear weapons. One is strategically sufficient for 96.

Unfortunately, there are a number of challenges with strategic sufficiency as a concept. Let me explain.

It should first be noted that nuclear weapons do not exercise effective deterrence simply by their existence in the American inventory, nor merely by matching friendly weapons to enemy weapons on paper. American planners need to go much further.

The US needs to base its nuclear deterrent arsenal size, and its nuclear deterrent strategy and posture, on a realistic evaluation of possible scenarios. Adversaries will certainly perform such risk analysis. If America’s nuclear readiness falls short, in their minds, adversaries may seek openings to attack.

The American nuclear deterrent needs to include survivable, damage-limiting, and damage-equalizing second-strike capabilities, against both numerous enemy armed forces and extensive enemy countervailing (political control) assets. The US should also have the ability to restore intra-war deterrence and to have leverage during post-war armistice talks, a significant further number of warheads and delivery platforms deployed or in secure stockpiles.

Strategic Sufficiency

In the webinar, Lowther offers as an illustrative case where China’s new missile field deploys three hundred intercontinental ballistic missiles (ICBM), each with eight warheads. In this case, strategic sufficiency may require fifty ICBMs to hold the three hundred Chinese missiles at risk. Dynamic parity, in contrast, would dictate the US should field an arsenal closer in size to China’s, which in this limited example would be 300 missiles with a similar number of warheads.

Admittedly, strategic sufficiency is attractive for a country with a smaller arsenal, but it is also attractive to an adversary with a larger arsenal. The adversary may see strategic sufficiency as a strategy of weakness and built on a lack of will. The approach has a number of flawed assumptions.

First, strategic sufficiency assumes that all American nuclear weapons will succeed in striking their targets and destroying them. While American delivery systems are reliable, they have no experience under the harsh conditions of a nuclear conflict. Some weapons may malfunction, others will be destroyed in a first strike, weapons may not hit their target, and some will be destroyed by enemy defensive systems.

This is why targeteers often allocate two or more warheads to one enemy silo, for example, which is generally considered necessary for a successful counterforce strike. On this count alone, strategic sufficiency underestimates sizing requirements.

Second, a more serious flaw is the assumption that the United States can always launch a counterforce first strike. An adversary’s remaining weapons will still be in their silos, or in their hangars, when American warheads arrive. This is a foolish assumption. The US is unlikely to initiate a first strike, which means it must be able to absorb a strike and respond. Strategic sufficiency does not allow that.

Making the situation much worse is that China, North Korea, and Russia possess nuclear delivery platforms that are mobile, making them far harder to strike. Ballistic missile submarines at sea are, for now, hard to strike. Mobile ICBM launchers move positions constantly, and might also be camouflaged, for example, while inside shipping containers or railroad freight cars. Strategic bombers can maintain airborne alert. Other ICBM launchers can be hidden inside caves or tunnels until the moment they are ready to fire.

Third, the US is highly unlikely, as said above, to employ nuclear weapons in a first strike. A number of wargames played by the military and senior government leaders only underscores the cultural aversion to nuclear weapons use. This means the homeland is likely to face a nuclear attack before the president responds with whatever nuclear weapons remain. If the American arsenal is already smaller than the arsenals of adversaries, the US becomes an inviting target for a second strike or a strike from a different adversary.

Fourth, strategic sufficiency gives allies the impression that the United States has too few weapons to defend North America and both Europe and Asia. This belief may lead allies to seek their own arsenals.

As McGiffin and Lowther argue, dynamic parity is designed to address these specific challenges. China, North Korea, and Russia are very clearly looking to topple the American-led international system. Should the United States seek to build an arsenal that is too small to effectively deter the Authoritarian triad discussed here, not only will Americans suffer, but so will the free world. Moving from 5 percent of the defense budget to modernize the current arsenal to 8 to 10 percent of the defense budget to build the arsenal needed is not in the “too hard to do” category. It is time to recognize that strategic sufficiency is not sufficient.
