Personally don't like trump, but he is destroying establishment in the US. He more or less is a wildcard that nobody predicted would win and he has gone onto to do some crazy things.
I think he is perfect for America at the moment, whilst Brexit is going to be wake up call for people in Britain.
Yes the establishment are deeply troubled by Trump and that can only be a good thing. So long as Trump keeps exposing and challenging the established order then he is doing the right thing. There is the anomoly of Syria but I believe he even played that as best he could, given the deep state's overwhelming pressure on him to act.
There’s been pressure on presidents before to do some weird things. You see the president is only a name, there is even a greater force behind the president that is pulling the strings therefore change is not easy.
