"Trump has suggested in years past that he believes a nuclear war is inevitable. So any tweet from him on this subject deserves great scrutiny—at least as much as his tweets about Alec Baldwin, SNL, and the musical Hamilton. The posting of this tweet, and his staff's inability to explain it, are frightening signs that Trump is not ready for the task of controlling weapons that can destroy the world."
