Do You Think Putin Is Going to Use Nuclear Weapons?

Vladimir Putin has put his nuclear weapons on a higher state of alert, says Peter Bergen. "What i'v found frightening about it and worrisome about it is not that he's going to use nuclear weapons," writes Bergen. The odds are extraordinarily small but I can't dismiss the person making that decision, adds Bergen. 'It suggests to me that even if he doesn't go there, he can go to a lot of other horrible places and dangerous places and destruct the places.'
