Kurt, my theory is that Saddam either destroyed, moved to another country, or hid the weapons before we launched our attack. He had ample time; months in fact. Our war machine grew at an agonizingly slow pace.
Iraq may be a real mess right now, and maybe we never will find the weapons, but you know what? The world is just a little bit safer now without Saddam and his fucked-up regime. Somebody needed to do it.
