How would you differentiate here between liberal democracy, illiberal democracy, straight-up undemocratic systems, and AI or similar NGOs simply liking the substantive outcomes of a particular government? For instance, I am by no means a fan of the Republican Party, but it's hard to believe that the United States of America was in 2005 a dictatorship or other authoritarian system: we lived through Bush peacefully transferring power to the Obama Administration, which was drawn from the opposite political party. It seems much more plausible that Amnesty simply didn't like how America was conducting the Iraq War, a substantive policy disagreement (and one I agree with Amnesty on). Problem is, that sort of demolishes the case that anyone Amnesty criticizes must, ipso facto, be an undemocratic authoritarian regime -- which I don't even recall Amnesty themselves claiming.
