Ukraine war: how the Biden administration is responding to Putin’s threats to go nuclear: Joe Biden has warned
that any use of tactical nuclear weapons in Ukraine by Russia could
lead to “Armageddon”. Speaking at a Democratic fundraising event in New
York on October 6, the US president said the crisis was the closest the
world had come to nuclear catastrophe for sixty years.
“We have not faced the prospect of Armageddon since Kennedy and the
Cuban missile crisis,” he said, going on to talk about Putin’s repeated
threats to resort to Russia’s nuclear arsenal if he felt Russia was
under threat: “We’ve got a guy I know fairly well. He’s not joking when
he talks about potential use of tactical nuclear weapons or biological
or chemical weapons because his military is, you might say,
significantly underperforming.”

The possibility of Russia using weapons of mass destruction
has hung over the conflict since Russian troops invaded Ukraine in late
February.
Several times – most recently after Russia annexed four Ukrainian
provinces and declared them part of the federation – the Kremlin
leadership has dropped heavy hints that they would use “all available
means” at their disposal to defend themselves, particularly against any
intervention from Nato.
This fits in with a key element of the theory of nuclear deterrence – the use of nuclear weapons as a threat, in this case to deter Nato from getting involved. When Biden declared in March he would not start “world war III” over Ukraine, this was taken as a clear reference to the risk of nuclear war.
