Hmmm... I don't believe hanging in the Middle East involves a platform, a drop, and instant oblivion.
Recall pictures out of Syria of pro-Israel spies who were decorated with large signs detailing their misdeeds, and then strung up in public with their feet just a little too high off the ground to interrupt the process.
A pretty slow way to go. Enough time for Saddam to reflect on what he might have done differently in life.
One would think he has had plenty of time to do that behind those bars.
Saddam will embrace death, just like the suicide bombers and the rest of the "martyrs". I doubt there will be a "light bulb" moment in which he thinks otherwise.
I heard on FNC that the gallows and the rope have been constructed specifically to break his neck quickly so that he will NOT linger but die muy pronto. It was the Americans who helped with that, I heard, but the Iraqis wanted it so that they could not be accused of cruel and unusual punishement. Whether all this is true I don't know, but it sounds plausible.
