President Joe Biden’s stark warning that the world faces the highest prospect of nuclear war in 60 years was not based on any new intelligence about Russian President Vladimir Putin’s intentions or changes in Russia’s nuclear posture, multiple US officials told CNN. The US still has seen no evidence that Putin is moving toward using Russia’s nuclear capability, nor is there any intelligence showing he’s decided to do so. But Biden’s comments, laid out in starker terms than other US officials have used to date, reflected heightened concerns inside his administration about the risk of Russia carrying out a nuclear strike in Ukraine, where Russian forces have recently faced a string of defeats. Former CIA Director Leon Panetta gives his reaction to CNN's Erin Burnett. #CNN #News
