I think The_Walrus had a good summary: the leader of Iraq was an aggressive dictator terrorizing his own people and his neighbors. Iraq was not a democracy and had already tried to invade a neighbor. Everyone world-wide had wanted the leader gone for a long time. But that wasn't the reason for the invasion. The stated reason was Iraq's failure to comply with an arms agreement prohibiting it from developing nuclear weapons. Nuclear weapons in the hands of sadistic dictator would, obviously, be a very bad thing. Still, I was NOT in favor of the war for a variety of reasons, and did not think we had a right to kick out the leader of a country no matter how hated. And, of course, it turned out that the intelligence we had suggesting they were in violation of the arms agreement was wrong, which is why the invasion looks pretty bad now with 20/20 hindsight. But understand this huge difference: Iraq was a war to topple a dictator, and the people of the country celebrated when he was gone. That is why Putin is working so hard to portray the government in the Ukraine as criminal, he wants to be able to play the same PR angle. Just, the world is smarter than that. The Ukranian people don't see Putin as a liberator, and they do not want him to "rescue" them from their government. Ultimately, it is as simple as that: what does the population of a country want? From that angle, even though the lens an outside nation can have will never be perfect, even though the US invasion of Iraq definitely had imperialist tones, and understanding we have long conceded the Iraq invasion was based on a lot of false data, the two invasions are completely opposite.
