During the campaign for the November election, candidate Trump disdainfully threatened to tear up the Iran accord. But as president, he has twice already certified to the US Congress that Iran is implementing its part of the deal. He is obliged to do it a third time by mid-October. Of course, Trump is not a stickler for consistency. He promised to wind up the Afghan war but approved a strategy for the open-ended war. Increasingly, he has exposed himself to be a man of straw.
