What if Ukraine had kept its nuclear weapons?

Some say Kyiv would have been in a better position today if it hadn't been disarmed following the fall of the Soviet Union.

Analysis | Europe

The nuclear disarmament of Belarus, Kazakhstan, and Ukraine was one of the great success stories of the end of the Cold War, and it was one of the most significant victories for the cause of nonproliferation. 

When the Soviet Union ceased to exist, these newly independent states had to manage the problem of the Soviet nuclear legacy left behind in their lands. Their disarmament was bound up with their status as independent, sovereign countries as they sought and needed to be integrated with the rest of the world. 

The commitment of the non-Russian republics to disarm saved the original Strategic Arms Reduction Treaty (START) and upheld the principles of the Non-Proliferation Treaty (NPT), and their eventual disarmament is one of the underappreciated achievements of U.S. foreign policy in the post-Cold War era.

While all three states were always willing to get rid of the nuclear weapons they had inherited from the Soviet Union, the paths that they took to disarmament were somewhat different with respect to the terms and timing of removing these weapons and their delivery systems from their territories. The Ukrainian case is the most involved of the three, and because of the war in Ukraine it is also the most salient today in current debates about disarmament and nonproliferation. It is therefore fortunate that there is a new book that can expertly guide us through this complicated and important history.

Mariana Budjeryn’s Inheriting the Bomb: The Collapse of the USSR and the Nuclear Disarmament of Ukraine is an excellent study of how the process of disarmament unfolded. Drawing on a wide range of sources, including some Ukrainian sources not tapped before, Budjeryn details in great depth the internal deliberations of the Ukrainian government and the intensive rounds of negotiations among the U.S., Russia and the three non-Russian republics. 

The book should become a standard reference for anyone working on this issue and on nonproliferation more broadly, and I expect that it will. 

Budjeryn shows how the Ukrainian government realized that they had no practical alternative to disarmament if they were going to be a full-fledged member of the international community, but they also believed that their country should not give up the weapons without receiving something in return. The Ukrainian government took a nuanced position on the question of disarmament, as they were committed to denuclearization but wanted, for reasons of sovereignty and leverage, to emphasize that they “owned” the weapons on their territory even if they couldn’t and wouldn’t use them. 

This insistence on ownership created some tensions in relations with both the U.S. and Russia, and opened Ukraine up to untrue charges of “backsliding” on its commitments. But in the end, Ukraine was never in a position to keep the weapons and did not want to keep them. 

One of the most fascinating aspects of the story is how the three non-Russian republics leveraged the U.S. desire to ratify and implement START into securing themselves places at the negotiating table. Russia would have preferred to keep all arms control discussions bilateral, but since START could not be implemented without the cooperation of the other states it became necessary to include them.

This created some interesting contradictions in Washington’s dealings with these states. On the one hand, Washington accepted that the three non-Russian republics were successors to the Soviet Union for the purposes of arms control under START, but it would not accept that they were successors to the Soviet Union’s status as a nuclear weapons state. 

The U.S. bottom line was that there should be no additional nuclear weapons states emerging from the collapsed Soviet Union. The NPT was clear that there could only be five nuclear weapons states, and the U.S. was not going to compromise on this point. This meant that Belarus, Kazakhstan, and Ukraine had to commit to joining the NPT as non-nuclear weapons states while simultaneously assisting the U.S. in eliminating part of the Soviet nuclear arsenal that they had in their countries.

 It took some time to get all three across the finish line with the ratification of both treaties, but it is a credit to their governments and to the Bush and Clinton administrations that they kept this process moving forward to a successful conclusion.

If Ukraine’s disarmament is discussed today, it is often mentioned as a supposed cautionary tale of what other states shouldn’t do. Shortly after the 2022 Russian invasion began, John Ullyot and Thomas Grant declared Ukraine’s disarmament to have been a mistake: “If you abandon your nuclear program and entrust your security to formal guarantees and conventional deterrence, you gamble with your future. If you give up your nukes, you give up your national security ace-in-the-hole.” 

Bill McGurn of The Wall Street Journal asked rhetorically, “If Ukraine hadn’t given up its nukes after the collapse of the Soviet Union, would Vladimir Putin have dared invade?” This line of thinking is misguided for several reasons. 

As Budjeryn shows, there really was no serious option of keeping the inherited nuclear weapons without exposing Ukraine to international opprobrium and isolation, and the cost of building up an indigenous nuclear weapons program to maintain their own arsenal was prohibitive. She sums up the Ukrainian foreign ministry’s view at the time: “The negative repercussions of the nuclear option would far outweigh the positive.” 

It is a mistake for people today to indulge the fantasy that Ukraine could have kept these weapons without suffering severe negative political and economic consequences, and it gives encouragement to would-be proliferators that our collective commitment to nonproliferation is waning. 

Another problem with the counterfactual is that there is no guarantee that Ukraine would have been made more secure if it had paid the high price to retain these weapons. If anything, possession of what would have been the world’s third-largest nuclear arsenal probably would have made Ukraine more of a target for interference and intervention, and the resources it would have had to pour into its nuclear weapons program would have come at the expense of its other defenses. 

Budjeryn quotes Boris Tarasyuk, Ukraine’s then-foreign minister, as saying, “For Ukraine to keep nuclear weapons would have been to go against the entire world order.” When critics of disarmament argue that Ukraine should have somehow kept this arsenal, they are ignoring the enormous, immediate costs that Ukraine would have faced for doing so. Ukraine would not only have been putting its good relations with the U.S. and its allies at risk by keeping these weapons, but counterintuitively it would have also risked its own survival. 

Budjeryn concludes: “If Ukraine had refused to join the NPT and kept a part of its nuclear inheritance, it would not be the same country it is today but with nuclear weapons. Indeed, it is doubtful whether it would be a country at all.”“Inheriting the Bomb” is essential reading for anyone interested in issues of disarmament and nonproliferation. It is exceptionally well-researched and well-written, and it deepens the reader’s understanding of the complex problems that were created by the collapse of the Soviet Union. It also reminds us of the importance of careful, patient diplomacy in managing multiple potential crises peacefully.

Blob exploiting Trump's anger with Putin, risking return to Biden's war

Europe

Donald Trump’s recent outburst against Vladimir Putin — accusing the Russian leader of "throwing a pile of bullsh*t at us" and threatening devastating new sanctions — might be just another Trumpian tantrum.

The president is known for abrupt reversals. Or it could be a bargaining tactic ahead of potential Ukraine peace talks. But there’s a third, more troubling possibility: establishment Republican hawks and neoconservatives, who have been maneuvering to hijack Trump’s “America First” agenda since his return to office, may be exploiting his frustration with Putin to push for a prolonged confrontation with Russia.

Trump’s irritation is understandable. Ukraine has accepted his proposed ceasefire, but Putin has refused, making him, in Trump’s eyes, the main obstacle to ending the war.

Putin’s calculus is clear. As Ted Snider notes in the American Conservative, Russia is winning on the battlefield. In June, it captured more Ukrainian territory and now threatens critical Kyiv’s supply lines. Moscow also seized a key lithium deposit critical to securing Trump’s support for Ukraine. Meanwhile, Russian missile and drone strikes have intensified.

Putin seems convinced his key demands — Ukraine’s neutrality, territorial concessions in the Donbas and Crimea, and a downsized Ukrainian military — are more achievable through war than diplomacy.

Yet his strategy empowers the transatlantic “forever war” faction: leaders in Britain, France, Germany, and the EU, along with hawks in both main U.S. parties. German Chancellor Friedrich Merz claims that diplomacy with Russia is “exhausted.” Europe’s war party, convinced a Russian victory would inevitably lead to an attack on NATO (a suicidal prospect for Moscow), is willing to fight “to the last Ukrainian.” Meanwhile, U.S. hawks, including liberal interventionist Democrats, stoke Trump’s ego, framing failure to stand up to Putin’s defiance as a sign of weakness or appeasement.

Trump long resisted this pressure. Pragmatism told him Ukraine couldn’t win, and calling it “Biden’s war” was his way of distancing himself, seeking a quick exit to refocus on China, which he has depicted as Washington’s greater foreign threat. At least as important, U.S. involvement in the war in Ukraine has been unpopular with his MAGA base.

But his June strikes on Iran may signal a hawkish shift. By touting them as a decisive blow to Iran’s nuclear program (despite Tehran’s refusal so far to abandon uranium enrichment), Trump may be embracing a new approach to dealing with recalcitrant foreign powers: offer a deal, set a deadline, then unleash overwhelming force if rejected. The optics of “success” could tempt him to try something similar with Russia.

This pivot coincides with a media campaign against restraint advocates within the administration like Elbridge Colby, the Pentagon policy chief who has prioritized China over Ukraine and also provoked the opposition of pro-Israel neoconservatives by warning against war with Iran. POLITICO quoted unnamed officials attacking Colby for wanting the U.S. to “do less in the world.” Meanwhile, the conventional Republican hawk Marco Rubio’s influence grows as he combines the jobs of both secretary of state and national security adviser.

What Can Trump Actually Do to Russia?
 

Nuclear deterrence rules out direct military action — even Biden, far more invested in Ukraine than Trump, avoided that risk. Instead, Trump ally Sen.Lindsey Graham (R-S.C.), another establishment Republican hawk, is pushing a 500% tariff on nations buying Russian hydrocarbons, aiming to sever Moscow from the global economy. Trump seems supportive, although the move’s feasibility and impact are doubtful.

China and India are key buyers of Russian oil. China alone imports 12.5 million barrels daily. Russia exports seven million barrels daily. China could absorb Russia’s entire output. Beijing has bluntly stated it “cannot afford” a Russian defeat, ensuring Moscow’s economic lifeline remains open.

The U.S., meanwhile, is ill-prepared for a tariff war with China. When Trump imposed 145% tariffs, Beijing retaliated by cutting off rare earth metals exports, vital to U.S. industry and defense. Trump backed down.

At the G-7 summit in Canada last month, the EU proposed lowering price caps on Russian oil from $60 a barrel to $45 a barrel as part of its 18th sanctions package against Russia. Trump rejected the proposal at the time but may be tempted to reconsider, given his suggestion that more sanctions may be needed. Even if Washington backs the measure now, however, it is unlikely to cripple Russia’s war machine.

Another strategy may involve isolating Russia by peeling away Moscow’s traditionally friendly neighbors. Here, Western mediation between Armenia and Azerbaijan isn’t about peace — if it were, pressure would target Baku, which has stalled agreements and threatened renewed war against Armenia. The real goal is to eject Russia from the South Caucasus and create a NATO-aligned energy corridor linking Turkey to Central Asia, bypassing both Russia and Iran to their detriment.

Central Asia itself is itself emerging as a new battleground. In May 2025, the EU has celebrated its first summit with Central Asian nations in Uzbekistan, with a heavy focus on developing the Middle Corridor, a route for transportation of energy and critical raw materials that would bypass Russia. In that context, the EU has committed €10 billion in support of the Trans-Caspian International Transport Route.

Lifting sanctions on Syria exposes their cruel intent

Middle East

On June 30, President Trump signed an executive order terminating the majority of U.S. sanctions on Syria. The move, which would have been unthinkable mere months ago, fulfilled a promise he made at an investment forum in Riyadh in May.“The sanctions were brutal and crippling,” he had declared to an audience of primarily Saudi businessmen. Lifting them, he said, will “give Syria a chance at greatness.”

The significance of this statement lies not solely in the relief that it will bring to the Syrian people. His remarks revealed an implicit but rarely admitted truth: sanctions — often presented as a peaceful alternative to war — have been harming the Syrian people all along.

The 8-point buzzsaw facing any invasion of Taiwan

Asia-Pacific

For the better part of a decade, China has served as the “pacing threat” around which American military planners craft defense policy and, most importantly, budget decisions.

Within that framework, a potential Chinese invasion of Taiwan has become the scenario most often cited as the likeliest flashpoint for a military confrontation between the two superpowers.
