Oh, and a quick note as well- what is falsely being characterized as a "civil war" in Iraq is, to the best of my understanding, actually now pretty much officially a proxy war between Iran and the Saudis (Dubyas pals)
I honestly believe that Saddams execution had 2 purposes- first, the US complicity in Saddams actions through the 80's could have gotten a few folks in trouble, so taking him out, all he knew died with him...
And second, the "civil war" would likely intensify, giving the US a sort of "out". The Saudis and Iran are funneling money and arms into the country and their respective factions are well represented throughout
In the end, Iraq will likely be split between the two, and since the house of Bush and house of Saud are real close, the original intent of owning at least part of Iraq will also be realized by proxy, in this case Saudi Arabia. That is what will happen, there is pretty much nothing that can be done to stop it, but the notion of "civil war" is a propaganda tool and nothing more, it is an actual war between age-old enemies, and the US role seems to have been merely to make it possible without much international intervention.
And agreed with finch and quoque, the execution itself was a shameful joke- the fact that George Bush said "fair trial" 3 times in the first 3 consecutive sentences of his "statement" is the first clue, and the fact that the US wrote the constitution and set up the courts means that no matter how much the administration insists to the contrary, it was the US who "tried", "convicted" AND executed him
