John Bolton.This super-hawk who terrifies even hawks, should never have been appointed in the first place. Since he became NSA almost everything in US Diplomacy has failed. Iran, North Korea, Israel and the Palestinians, Afghanistan, China Trade War, the list goes on. Promises, expectations and many, many tweets but so little actual progress anywhere.
The President knows his own day of reckoning is coming. He must get something he has promised closed out and settled by November 2020. Or else early in that month he will have a very bad day. Getting rid of John Bolton has given him a chance of a more joined up approach to all these many difficult issues. His backers will hope this begins to lead to results. Otherwise he will be remembered as the tweeting president who, after cutting a few regulations and fixing tax cuts for the rich, killed the economic boom he helped to create and delivered almost nothing else he had promised.
Having said that, if Trump fails to win a second term, there will be very few people in the wider world outside America who will be sorry.
