The trial is going to be a repeat of Ceaucescu's. My bet is Saddam is going to become extremely delusional, thinking that he's still in power, the people still love him. Like the "Genius of the Carpathians", then Saddam will meet his end immediately after the trial.
He was obviously delusional when he came out of the hole. Like Ceaucescu, right now he is thinking he is still invincible. Wait til he gets the whole picture...then his sociopath self will out.
