Re: Schrödinger's Embassy
Trump is only "big on loyalty" one way. He cares passionately that people are loyal to him, but he shows no sign of recognising any obligation to return or reward that loyalty. See: all the people he's dismissed (or have quit) from his campaign and/or administration and then disowned, with varying degrees of disparagement and vehemence.
I'm pretty sure Trump would claim him if he thought it would give him a diplomatic triumph he could tweet about. "Winning" is all he cares about. I also wouldn't put it past him to make the attempt even if he knew it only had a small chance of working, because "losing" doesn't cost him anything either - he just blames it on his innumerable enemies (who are, of course, no fault of his, they're completely evil and irrational).
