I'm sick of this old line. People treat our Intelligence community like idiots. Of course there was evidence, we just don't know where it went. The media distorts so much we no longer know what's true or not.
Having said that, do I think we need to die for people who have been at war for eons? NO! Let them fight their own, and if they don't and are taken over by radials, oh well, that's their choice. BUT, I do believe we need to protect those who want no part of this war (those on the fringes).
There sure was evidence, but Saddam kept moving the WMDs around from one hiding place to another, and then just before the war to Syria
