Just something MAGA-people seem to have a hard time with sometimes. Probably not as much when Americans are speaking to themselves, but as a non-American, sometimes it’s challenging to get “those people” to admit that there is indeed anything wrong with the US. As in they won’t accept a single criticism, and will loudly proclaim “America is the greatest country in the world”, while wearing a “Make America Great Again” hat, which for me pretty explicitly means America isn’t great, if it has to be made to be such again.
I think an important related aspect is that the ‘unfortunate things’ that happen make it only “not quite as great” but are definitely destined to make it “the worst”. That way there’s a sense of urgency that you wouldn’t otherwise get from just “not quite as awesome as it could be, but still the best”
