How North Korean diplomacy fails
North Korea has expressed willingness to discuss denuclearization with the U.S., a significant step that President Trump has greeted on Twitter with cautious optimism. The news follows talks between North and South Korea, and a show of unity at the Winter Olympics.
There's reason for skepticism: The diplomatic history shows that apparent breakthroughs and shows of good will have proved fleeting, particularly surrounding major sporting events. Even now, North Korea maintains it won't discuss denuclearization, which the U.S. says must be a starting point for talks.
