I don’t think they’ll evaporate per se. The shias will put up somewhat of a fight. But we have 2 sides involved that both hate America with the Iraqi gov’t being ambivalent. Iran isn’t going to help us. ISIS ain’t going to help us. The embassy is essentially waiting for someone to pluck it. Whether it’ll be Iranians or ISIS. Who knows.
I don’t care. If Muslims slaughter each other, that’s good for us.
Fewer of them around to slaughter us. They both hate us and as the old saying goes, no good deed goes unpunished.
May their internecine warfare last forever and may both sides lose.
