Burns warned that officials should heed Putin’s threats to use tactical nuclear weapons. “We have to take it very seriously [any] kind of threats, given that it’s at stake,” Burns said in an interview with CBS News’ Norah O’Donnell in late September. “And, you know, the rhetoric that he and other senior Russian leaders have used is reckless and deeply irresponsible.” Russian military leaders’ talk of nuclear attack rattles US calculations Burns added that US intelligence agencies have yet to see “any practical evidence” that Putin is moving closer to using nuclear weapons. That has been the case during the war, with Putin making threats that officials say have not been reflected in signs that Russia is developing the equipment and personnel necessary to use such weapons on the battlefield.
