Well, I don't know if Trump has scared the North Korean leadership -- I doubt it -- but I know that he's certainly scared me.
What I would like to see now is the Secret Service bundling him into a straight-jacket and dropped off on Guam, or perhapps Seoul. It won't happen, of course, because we always protect the leader , even if that's who got us into the war.
Next best would be super-Christian and uber- Mormon Pence saying Okay, thats it, fuck it, you're clearly wacko, 25th Amendment, hustle his ass out of here, but since he's such a smiling, nodding, go-along kind of guy who can probably tell you the exact number of days until the end of term (including the asterisk which reads 'unless impeached or otherwise removed from office), the chances of him stepping forward and taking any kind of forceful actionare pretty minimal.
As are the chances of the Congress doing anything useful.
So I hope we'd not fucked, but I'm not counting on it. Bastards.
