President Donald Trump drew gasps at the United Nations General Assembly last September when he threatened to "totally destroy" North Korea.

Eight months later, he said "everyone" thought he should get the Nobel Peace Prize for a new approach to North Korea that aimed to put him at a table with its leader, Kim Jong Un, to negotiate over denuclearization.

Now that planned meeting, scheduled for June 12 in Singapore, is off, capping a months-long back-and-forth with nuclear-armed Pyongyang and denying Trump the foreign policy victory he craved.
