Saddam Hussein missed his chance, all right. If he had given up power and moved elsewhere he could have looted the country's treasury AND become a martyr, giving it all up so that his country could have peace.
He could have then been a hero to many and spared them much death and destruction.

(Please note that I am not in any way discussing the "rightness" or "wrongness" of what the US, etc. are doing.)

This cannot be a war, as it was not constitutionally declared. Congress seems to be composed of gutless wonders these days -- and we call them "leaders."
