Well yes, advisors from his party, who millions of people voted for - it's the same as tories ans Labour over here - most of the people from whichever side gets in are well intentioned intelligent people who will do their best for their country. The side you didn't vote for will probably persue some policies you personally don't like, but a lot of other people do. Then four/five years later those policies are judged and either carry on or the other lot get in and the balance goes the other way.
The world doesn't end, good and bad stuff still happens.
Trump won't abandon NATO but will pressure the European states to up their defence budgets so America doesn't feel it's carrying everyone else. He won't outlaw abortions either. He won't build a wall. He won't be perfect and will probably introduce an equally crap alternative to obamacare, and some other stuff some people won't agree with, but every government in history has done that anyway and the world will generally carry on spinning.
Life's too short for throwing a paddy every time something goes differently to how you'd like. Wait and see what happens and then judge - there's buggerall you can do about the American election anyway.
Maybe I'm too old, just seems like a massive overreaction.
