Comments appear to significantly lower the threshold for Russia to use nuclear weapons and come as Western allies consider allowing Ukraine to use weapons inside Russia.
Russian President Vladimir Putin has warned that Russia could respond with nuclear weapons if it were attacked with conventional arms in the latest changes to the country’s nuclear doctrine.
In a televised meeting of Russia’s Security Council, Putin on Wednesday announced that under the planned revisions, an attack against the country by a non-nuclear power with the “participation or support of a nuclear power” would be seen as a “joint attack on the Russian Federation”.
Putin emphasised that Russia could use nuclear weapons in response to a conventional attack that posed a “critical threat to our sovereignty”, a vague formulation that leaves broad room for interpretation.
“This is a signal that warns these countries about the consequences if they participate in an attack on our country by various means, and not necessarily nuclear ones,” he said.
