The 'rats simply don't understand that we are fighting a real war against a deadly and ruthless enemy. We can't just declare the war over and go back to ogling Paris Hilton full time. The enemy has other ideas.
They can blame Bush for future attacks all they want. When there is a mushroom cloud over Detroit or San Fransisco or an American Beslan the people will demand a government dedicated to decisively ending this conflict once and for all. That government won't be headed by Pelosi, Reid, or Clinton....
No big deal. They figure they can surrender our country and help the enemy and that the new power structure will reward them and they'll be able to live out their lives in comfort elsewhere. They probably figure that in a worst case scenario they could be on a plane to Barbados with fat bank accounts and live out their lives there. The resulting ethnic cleansing of Christians, Jews and all other "offensive" groups back here will just be something they see on the evening news in their new homes.
