What should happen to saddam if he is found guilty?:
The Americans have been gunning for his death all along, and
will defiantly impress upon the tribunal to give the Death penalty.

But you must also know, that even today Saddam is a feared and respected man by many in Iraq.The outcome will not be settled so fast. Did you see the Glaring eyes & stance when in court he recently told the judge"I am the ruler of Iraq and who are you, a foreigner trying to pass judgement on me?"

The recent spate of bombings in Iraq between the Shias and Sunnis is directly connected with Saddams case. Which country
would ever allow a foreign country to set up courts?

No. The chair will probably decay &break, and the switches/
wires will rust or melt away.And dont suggest a rope, because there is no such strong rope exists in the World to snap such a
strong throat.
