Trump's diplomacy (whoever's actually dictating it, presumably not Trump himself) looks to be the most murderous US intervention in foreign affairs since Henry Ford put Hitler into power.

His speech will interpreted by his hosts as all-out, no-questions-asked backing for genocidal war against Shiism. Hence the explicit staement that the US has no problems with the repressive regime in Bahrain, and more importantly, he's equipping the Saudis to exterminate the Shiite population of Yemen, where millions are at risk of famine. And beyond that, he wants to start a proxy war with Iran.

The result is going to be millions dead, far worse than the Holocaust.
