President Saddam — Again?

During the buildup to the war, and since, many who opposed the war declared it an “illegal” action and a violation of international law.
Now that he has been found to be alive, I’d ask this to those who considered this an illegitimate war: will you now stand up and demand that Hussein be placed back in power? He was, after all, the “legal” ruler of Iraq.
And if not, why not?
