If you'd like to view a bit of evidence showing that the right wing of the Republican party was vitally interested in Iraqi "regime change" long before 9/11 and long before any supposed Hussein-bin Laden connection, please click the link below. This will take you to a letter written to then President Clinton and signed by well known conservative figures. The letter is posted on a conservative web-site.
I think this letter tends to show that conservatives have a long standing passion to remove Hussein, and that they are using 9/11 and the terrorist threat as a convenient excuse for pursuing that end.
