LOL!
One such narrative is, "Bush lied; people died." The claim is that "neocons," including Feith, politicized intelligence to show that Saddam Hussein's regime had weapons of mass destruction. Not so, as the Senate Intelligence Committee and the Silberman-Robb Commission have concluded already. Every intelligence agency believed Saddam had weapons of mass destruction, and the post-invasion Duelfer report concluded that he maintained the capability to produce them on short notice. There was abundant evidence of contacts between Saddam's regime and al-Qaida and other terrorist groups. Given Saddam's hostility to the United States and his stonewalling of the United Nations, American leaders had every reason to believe he posed a grave threat. Removing him removed that threat.
It was not the fighting of the war that was poorly executed. It was the politics of the war that was abysmal.
So far as LP/CPers, they are simply wrong both constitutionally and pragmatically in their understandings of war and isolationism.
