While GWB overthrowing an authoritarian government in Iraq on a lie is really bad, it does not rise to the level of overthrowing a liberal democracy in America on a lie. Yes, both were lies, but Bush barely had to lie at all to get the Congress to go along with it and one could make the case that he believed the lie himself. Not so with Trump, as the indictment makes clear.

If you read the Mueller Report it's also clear the the "Russiagate" wasn't a hoax and this argument that the "Democrats had their chance to hit Trump" as if the fact that the impeachments clearly failed on a partisan basis and Barr misrepresented the findings in the Mueller Report, which were damning and would have been worth an indictment if not for the fact of Trump being the sitting President at the time.

If you hate the American system and think the current liberal democracy deserves to be destroyed (for whatever reason) then you can just say so without pretending that Trump isn't a uniquely malignant liar beyond precedent.
