Former Secretary of State John Kerry said President Trump's rhetoric has "stepped over the line" and has "given North Korea a reason to say, 'Hey, we need a bomb.'
"I think what the president needs to do is make sure he's not feeding into North Korea's fear of regime change, or of a unilateral attack, or otherwise," Kerry said in an interview with CNN's Christiane Amanpour.
"And I think the rhetoric to date has frankly stepped over the line with respect to the messages that are being sent," the diplomat said. "It's given North Korea a reason to say, 'Hey we need a bomb because if we don't have a bomb, we're going to, you know, not be able to protect themselves and they'll come after us.'"
