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.

There are real issues that the president Donald Trump and particularly Steve Bannon, his political adviser, are pushing. It's a vision, a rather dark vision, of a 19th century world where great powers do transactional issues.

I know that presidents often have really bad phone conversations. What they usually don't do is go out and talk about it. That gets to my point about doing some damage on the periphery of our core policies.

The Iraqi government and most Iraqis understand that they have to bring back the Sunni Arab 20, 25 percent of the population. It won't work with these Shia militias running amok in these areas.

Optimism is in short supply in the Middle East, but what I do think is the administration needs to step up its act. We should use military strikes against ISIS when they threaten the Shia areas or Baghdad. We need to accelerate very rapidly, and we have ways to do it, aid to the Syrians, and we need to be more active, with results, not simply inputs. That is absolutely important right now, because people are questioning our will, not our capabilities.

The NATO alliance is not just a transactional relationship, once again. That alliance serves our interests. That alliance has been critical to keeping security in Europe, so that we do not face another world war.
