The North Korean rhetoric

There is such an effort to portray the North Korean rhetoric as crazy and irrational. The statements of the North Korean ambassador in Geneva contain some explanations for the real and legitimate fears that his country has vis-a-vis US growing nuclear threat.  If the two US and North Korean leaders can't be trusted with nukes, the rhetoric of the US in the last few weeks have been more crazy that that of the constantly mocked rhetoric of North Korea.
