This is the secret genius hypothesis. I don't give it much credit, considering how the administration is flailing on almost every other front. It is possible that all of this was Trump being very clever. But it is as easily explained by him being an impulsive fool, and that explains all the rest as well. But if he keeps on making big foreign policy gains like this, then I may have to reevaluate.

FWIW, this definitely caused me to up my estimation of him. It went from "absolutely dismal," to "very bad." I'll also note that it's just a bit too early to tell whether this will ultimately result in a good outcome. Shaking hands is a big step. But actions talk louder than photo ops.
