Bush said Saddam's execution sent a confusing message. "It basically says to people, look, you conducted a trial and gave Saddam justice that he didn't give to others," he said. "But then, when it came to execute him, it looked like it was kind of a revenge killing ... It just goes to show that this is a government that has still got some maturation to do."He was talking about the al-Maliki government, by the way.
Note the words carefully. Bush is not concerned with whether or not it WAS a revenge killing, he is concerned with how it LOOKED.
Obviously, Bush knows full well that this was a revenge killing. After all, from his own point of view, wasn't that the whole point of this Iraq War adventure - to kill the man who tried to kill Bush's Daddy?
Bush's words also lend credence to the widespread belief that al-Sadr was personally involved in the lynching of Saddam.
