John Bolton hasn't seen a war he doesn't love. This pathetic fucking slime bucket is right up there with Cheney, Rumsfeld and the rest of the right-wing, draft-dodging cowards, with his warmongering... no wonder Trump, who's a draft dodging coward, himself, would choose him.
Similar to George W. Bush, who named him UN Ambassador in 2005, Bolton did serve in the military, but his thirst for war is unmatched, especially pushing for regime change in Iran right now, which is something Trump is certainly committed to doing, and Bolton will push the issue very hard.
