It is not always a bad thing for political leaders to give the impression that they are unpredictable. It makes it much more difficult for their enemies to calibrate responses. But Donald Trump is not unpredictable in a good way. He is erratic. His aides have no way of assessing what his next move will be. As a result, they can't plan ahead. Do they have any idea what they're going to do next, now that they moved the Syria conflict into a new phase? I doubt it very much.
