"Making a statement about tactical nuclear weapons in Belarus, he admits that he is afraid of losing & all he can do is scare with tactics," Mykhailo Podolyak tweeted. Washington, the world's other nuclear superpower, played down concerns about Putin's announcement and the potential for Moscow to use nuclear weapons in the war in Ukraine. The official noted that Russia and Belarus had been speaking about the transfer of nuclear weapons for some time. However, the International Campaign to Abolish Nuclear Weapons called Putin's announcement an extremely dangerous escalation. Sharing nuclear weapons makes the situation much worse and risks catastrophic humanitarian consequences," it said on Twitter.
