As a longtime career guy, I like quiet diplomacy behind closed doors. This is not what we're getting with Donald Trump. At the end of the day, it's what America does, how people perceive us, in the long run, our reliability and such, and, thirdly, the personal relationships presidents have with their counterparts. The tweeting and some of the explosive conversations can hurt the third and can have an impact on the second, but, in the end, what we really should focus on is the policies. Some of them have been bad, the rollout of the immigration ban. Others, we have to wait and see.
