The world has nothing to benefit from the United States of America - they will keep it burning in every sense !
Whether it is Obama or Trump, the United States and their lackeys- the French, English and others, will not bend. It is below them to have a discussion with the rest of the world. The UN is a place for them to keep the Japanese and Germans from dominating the world scene. Russians and Chinese will do anything which suits their whims - so countries like us and the middle east countries will try and find refuge with them.
There is a good reason why the Iranians hate American politicians. Not many know that Eisenhower and Dulles engineered the coup in 1952, which replaced the democratically elected Mohammed Mossadegh with their puppet Shah so that they their access and control on oil fields isn't disturbed. They had understood by then that oil and fossil fuels will drive the world economy.
Every now and then, the US will have a Reagan or Trump even if he is not elected, who will provide an excuse for the so called moderates to say they are trying to do their best.
