With adversaries, Trump’s underlying unpredictability and lack of understanding of how to use the tools of American power will now be exacerbated by the lack of much in the way of experienced and judicious foreign policy advice and implementation ... So I think there’s added room for the kind of misjudgment and misinterpretation (on both sides) that leads small incidents to escalate into major international crisis.

You know, from the moment Mohammed bin Salman was appointed defense minister at his tender age, I have heard voices from around the gulf expressing a desire to see more experienced foreign policy hands advising him. At the end of the day, the proof of the pudding is in the eating. He can have all the good advice he needs, but he's got to take it.
