Ok. Primarily the Insurgents in Iraq do not want America there. This is a given. They feel we had no right to come in and change their way of life. And we were wrong to go in and oust Saddamn. Ok, makes sense. So they fight us because we destroyed the old government. And the insurgents have seemed in recent months to have been ProSaddamn. Ok... Read this.

Masked Gunmen kidnap and kill one of the DEFENSE Lawyers for Saddamns Right-hand-man. So....

The Insurgents kill Americans because we take Saddamn out of power... Then kill those who are trying to keep Saddamn out of prison/the gallows.

Right...it was obviously the insurgents.

>What is it that they want!?

The Saudi Arabians want to fight the "great devil", the Sunnis don't want a Shiite-dominated government, the Shiites want revenge on the Sunnis, the Kurds on the Arabs, local gangs are in it for the loot, and everybody wants the invaders out.

>The Insurgents kill Americans because we take Saddamn out of power... Then kill those who are trying to keep Saddamn out of prison/the gallows.

"The insurgents" kill Americans because they hate Americans, not because they like Saddam. Likewise, "the Insurgents" kill Saddam-supporters because they hate Saddam, not because they like Americans.
Your problem is binary thinking: Anti-Coalition<=/=>Pro-Saddam
