I say good riddance.

Saddam wanted to be shot by U.S. troops, since that would be an honorable death at the enemies hands.

But he doesn't deserve an honorable death, so he got a quick and violent death.

And the comparisions to Bush and Blair don't hold.
Bush and Blair were acting in the interests of the nations (no matter what you may think, can you see inside their heads?), Saddam was acting in his own interest.

And at the time of the 9/11 attacks, everyone was for going to war on terror. Including you, I'm sure.

EDIT: However, I do wonder if he had any regrets *other than losing the war in the first place*... It'd be interesting.
And CryoDragoon, I personally don't see how you could call him a human being, after the atrocities he commited, all in his own name.
