My wife thinks I worry too much about John Bolton. She views Trump as being similar to people who get married and divorced multiple times; the churn gets faster as the partners get disillusioned more rapidly. In her opinion, Bolton will leave quickly as soon as he figures out that he doesn’t have the magic ability to manage his boss, because he is beyond management. That means we shouldn’t attach too much importance to any Trump appointment, even one as odious and potentially dangerous as Bolton.
It’s an interesting analogy, and it deserves to be taken seriously, particularly since Trump has had multiple wives. However, I don’t think it holds up, in that the first crop of “adult” advisers was largely imposed on him; it is natural that he would feel more comfortable with the second wave, who, in turn, have a better sense of what it is he wants–not real advisers, but mouthpieces who can anticipate his changing moods and shine on TV. They will have considerable difficulty dealing with his mercurial moods, and many of them won’t last, but I don’t think the churn will be ever faster. What you will see instead is an administration staffed by unqualified adventurers with no reputation and little to lose, because no one else will be willing to work there.
