And I should add, so people don’t peg me as an isolationist, I supported the Iraq invasion. Hell, I still say we won the war. But with any military action, I believe in going in, kicking ass, and getting out. The global love cop stuff, the Wilson/Clinton-esque nation building always ends badly unless the populace en masse fights for their own freedom. And BTW... screw democracy. This is a republic, or is meant to be.
Being the "World's Policeman" is BS regardless of the party in power. That said, we DO have strategic interests in the stability of Iraq and Iraq IS a "Roach Motel" for jihadists!
