Putin spokesman refuses to rule out use of nuclear weapons if Russia faced an 'existential threat'

Russian President Vladimir Putin's chief spokesman has conceded that Russia has yet to achieve any of its military goals in Ukraine and refused to deny that Moscow could resort to the use of nuclear weapons.

In an interview with CNN's Christiane Amanpour on Tuesday, Dmitry Peskov repeatedly refused to rule out that Russia would consider using nuclear weapons against what Moscow saw as an "existential threat." When asked under what conditions Putin would use Russia's nuclear capability, Peskov replied, "if it is an existential threat for our country, then it can be."

Putin has previously hinted at using nuclear weapons against nations that he saw as a threat to Russia. Back in February, the Russian President said in a televised statement, "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."
