Before he was threatening Kim Jong Un, he was telling the South Koreans that maybe it’s time to reconsider the US troop presence and that they’ve got to start paying for their own defense. What Trump really cares about is domestic politics: immigration, taxes, and infrastructure. Wait until he gets his hands on the money he plans to spend on new roads, airports, etc.: then you’ll see the President in his element, wasting huge amounts of money on monuments to himself.

If there's risk of real war, expect it to come from the State department and the CIA, most likely aligned with the Saudi crazies.
