Saddam headed a terrorist regime. He was a terrorist, and so was his country, even before 9/11.
After 9/11 the US declared a war on terrorism. Iraq was probably one of the top three terrorist regimes the US should have started on, just by looking at its history of agression made the case stronger to start on Iraq. Also the fact it didn't condemn 9/11.
It harbored terrorists, funded them, and incited them. I am not saying Iraq had something to do with 9/11, but it doesn't matter to me. It is not a war on only those responsible for 9/11, a war just on Al Queda, or a war just on WMD. It is directed against all terrorists. So the argument leftists say about Iraq having nothing to do with 9/11 is foolish, because this is not what this war is just about - it is more than that.
My only hope is that the US declares war on militant Islam.
