The fact is that Donald Trump is going to be the president of the United States of America on January 20th, 2017. At best nothing too terrible (but it’s still going to be awful) is going to happen during the next four years, at worst everything will go to hell and then it will get worse. Whatever the outcome depends on what happens, but the signs so far are not good at all.
It clear, at least in my view that Donald Trump is going to service his own agenda first and the U.S second (maybe the third). I guess most things are going get stuck in the U.S congress, both houses for a long time and that is going to create all manners of problems. The Office of U.S President has considerable power in several fields that I suspect that is where Donald Trump is going to use his power for his own gain. Unlike many countries, this is not just a figurehead or ceremonial office, it has real power besides vetoing law bills from congress. That power is now up for abuse and corruption and that is going to happen, on how big of a scale and how badly is not possible to know, but it is going to happen.
At worst Donald Trump is going to start a recession in the U.S, I don’t think the rest of the world is going to be too much affected due to the 2008 recession and the safeguards the EU for instance has put in place. It is going to be a major inconvenience for many countries and the EU. Russia economy would not survive such event at all, regardless of ideas otherwise.
As for Donald Trump promises, he won’t do any of them, none, zero, 0. That process has already started as reported [warning!Auto play video in this news] by The Independence (UK) news website. From the day Donald Trump takes office on January 20th, 2017 and until the day he leaves office (one way or an other) it is going to be nothing but corruption and scandals. How big and how bad remains to be seen, but the wait is not going to be long.
