Yes, the US Iraq war was 100% a crime against Iraq and humanity. If we did the Iraqi people a favor, as the dogs of war insist, then we owe Iraqi's nothing and can walk away anytime. In any case, we've been "nation building" for well over a decade, do we ever get to leave?
But, the Kurds vs. Turkey thing has nothing to do with America, nor America's attack on Iraq. The Kurds are terrorists who have been attacking Iraq and Turkey long before the Iraq war. The US occupation of Iraq just caused the Kurd vs. Turkey fighting to pause.
Nope.
