The US president Joe Biden says Russian president Vladimir Putin isn’t "joking" when he talks about using nuclear weapons. There could be nuclear ‘armageddon’ he claims. "For the first time since the Cuban Missile Crisis, we have a direct threat to the use of nuclear weapons, if in fact things continue down the path they'd been going" The White House said that Biden’s warning was not based on new intelligence suggesting an imminent nuclear threat. So is the west overestimating Putin’s intentions or will he end this war by using nukes?
