“The risk of global nuclear war has practically disappeared,” Mikhail Gorbachev, the last leader of the Soviet Union, said in his 1991 Nobel Prize acceptance speech, even though Russia and the United States retained their massive nuclear arsenals.

Three decades later, nine countries are members of the nuclear club. Even so, many were reassured last summer when Russian President Vladimir Putin and US President Joe Biden during a Geneva summit reiterated the Gorbachev-Regan statement that “a nuclear war cannot be won and must never be fought.”

But ever since Russia’s late-February invasion of Ukraine, political leaders, nuclear arms control experts, and world citizens have tried to answer some version of the question: Will Putin use nuclear weapons in his war in Ukraine?

The utterances by individuals of note listed below might have been responses to this question. These statements, arranged chronologically, offer a still-unfolding existential narrative on whether nuclear war may or may not be imminent.

Author’s note: Dates refer either to the date the statement was uttered or the date it was published.

Will Putin deploy nuclear weapons in his war with Ukraine?

    “No matter who tries to stand in our way or all the more so create threats for our country and our people, they must know that Russia will respond immediately, and the consequences will be such as you have never seen in your entire history,” President Vladimir Putin said in a statement widely interpreted as a nuclear threat.

    “The risks of a direct confrontation between US and Russian forces may be fairly low at present,” Michael Dobbs, author of One Minute to Midnight, an account of the Cuban missile crisis, said. “But if you multiply that by X months or X years and the number of things that could go wrong, they turn out to be similar mathematically [to the one-in-three nuclear-war odds that President John F. Kennedy had calculated during the Cuban Missile Crisis].”

    “We have a special document on nuclear deterrence.

All the above arguments against this conflict becoming nuclear are based on the assumption that Putin is a rational being. The same assumption was applied to Hitler prior to WW II. Mathematical analysis based on applying chaos theory to the history of major recent conflicts indicate that there is a serious risk of WW III and massive loss of human life arising from escalation of this Russian invasion. As someone whose first memories are of German flares and bombs dropping on a small village 8 miles from their target of Cardiff docks in Wales, I beg all with any influence… Read more »

Unfortunately, Boris Johnson and USA keep provoking Putin. The threat to use UK weapons in Russia is inexcusable. People who want to escalate the conflict the compare Putin to Hitler. Ok, if this comparison stands, we all agree that a desperate Hitler would use atomic bombs before killing himself, what about a desperate Putin?

I can only apologize on behalf of my fellow, sensible Brits to Europe and the world that he is our PM. I, at least, along with many others have a clear conscience in that I didn’t vote for his party at our general election in December 2019.

If he loses, will he feel betrayed and abandoned by a world unworthy of him? Will he feel weakened and shamed on a world scene? Loss of Face! Narcissus does not tolerate dagger in heart, no way, not like some people. Dagger in heart of Narcissus is betrayal! If he goes down, will that mean gross loss of face? Exactly what will that mean to him? Will he consider taking a generation of unworthy ones with him?

If he wins, he’ll do a victory lap, whatever that means to him, and to those who are in awe of him.

Russia is in fact subtlety threatening to use nukes. It is likely to use tactical nukes if 1) it is losing the war, and 2) Ukraine escalates its attacks on Russian territory. Ukraine and the West probably will not moderate their actions in the face of this threat because that would encourage other countries with nukes to “blackmail” adversaries by threatening to use nukes. Thus, Russia is quite likely to use nukes. If it does, the West’s reaction is uncertain, but it is likely to be very strong in order to discourage further use of nukes by Russia or others.… Read more »

Interesting to see the tone shift the farther you go down the timeline. I do believe Russia is becoming more desperate in attempts to show the west its capabilities and strength as a country. I fear the most likely outcome would be the utilization of a smaller more tactical nuclear strike on a Ukrainian city just as Scott Sagan said.

It appears that if wmds are deployed they would be tactical and in the strategic context like that of Hiroshima and Nagasaki.

The pattern of Russian actions suggests likelihood of use of a tactical nuke using a hypersonic missile. Russia has used its limited supply of hypersonic missiles more than once to attack targets in Ukraine. Why would they do this? A highly logical target would be to hit Yaroviv with a tactical nuke well under 0.5 kiloton yield. Russia has hit this base with a conventional warhead but not a hypersonic missile. https://www.rferl.org/a/russia-missiles-base-ukrainian-border/31750540.htm. This is the base thru which Western weapons flow and Ukrainians have been trained. It is close to the border of Poland. A tactical nuke strike there could significantly damage the facility but more… Read more »

Putin is holding the world hostage with the ongoing fear that he might use nuclear weapons. That makes all of us his slaves, his bitches, his dogs: we dare not fully oppose the violent conquest of a sovereign nation out of fear of this Bully In The International Playground. If Putin succeeds, he will continue. If this invasion of Ukraine is not stopped, firmly and decisively, the door to ongoing conquest opens – and not just by Russia. Putin is testing whether or not threatening nukes is the secret to absolute power over the world, the key to open, unopposed… Read more »

I strongly believe Putin will either go nuclear, chemical, or biological. However, I do not think he’ll launch on a nato country. It will be on Ukraine soil. And I do not see nato launching in retaliation but will lead to nato troops in Ukraine. Or a no fly zone
