@bob @Elizafox unfortunately, I don't think so :/ I think impeachment is unlikely to begin with, but even if it does happen, there's an entire military-industrial complex that demands a new war. It's not just republicans with "skin in the game," so to speak. Regardless, the rest of Trump's admin shares most of his goals, and will benefit from a common "enemy" to unify the country under their fascist leadership.
@Elizafox @bob Oh, absolutely. Part of what makes this whole mess so frightening is that people on both sides of the aisle have interests in escalating the situation, entirely separate from Trump as an individual. It's not like republicans have a monopoly on warmongering by any means; Obama was as bomb-happy as any president, if not moreso.
Also, for the record, I think that having Mike Pence replace Trump would be much worse.
Intimidating NK is not very wise, but Trump needs an external enemy if he's to avoid the inevitable backlash when the white working class jobs he promised don't materialize. He doesn't have many establishment allies and so he might be more inclined to do desperate stuff.
