(start over. or just start yelling: )

There was no uranium
There was no anthrax
THere was no smallpox.
There was no vx gas. No sarin
Iraq was not guilty of 911.
Iraq had no connection to al qaida.
There was no excuse for the war.
It was not self defense,
It was naked aggression,
The war was a fraud and the war was based on lies.
There is no reason to be there, and
The u.s. should get out. Right now.
