IMHO, the moment it became crystal clear that Bush was a shitty war time president came when he let Muqtada al-Sadr off the hook, indirectly and eventually enabling the Iranian mullahs. Like feral animals, feral countries should have offsetting natural enemies and idiot Bush took down Iran's natural enemy, giving the mideast another, more dangerous nuclear power. He was exactly what the dems said of him - stupid.
Yeah, he made mistakes but he did take the war to Osama and troops instead of being like Obama who tied the hands of our troops so tight it was almost impossible to kill a terrorist. Fortunately Pres. Trump has untied their hands.
