It's a pity, this potentially serious subject is presented with complete disregard for alternative views. Either it's "far worse" or your just being delusional. Mirza, I understand that you have your beliefs, and that in itself is beautiful, but I urge you, don't be so quick to assume that you are correct and all who oppose are just idiots or evil. People aren't just some static characters found in books.
Whether we messed up in Iraq or not (which we didn't) is irrelevant to the question, which is asking if it was worse than Russia's invasion. Russia attacked Ukraine out of its imperialistic nature, and is trying to annex the eastern half of it. America has never intended to annex Iraq, so their invasion was done on a much different level.
