The problem with the US is not the regime, it's the people. We elected Trump a second time with ~50% of the vote after seeing four years of his complete buffoonery. His approval rating is still around 40%. If he were somehow to run again in 2028 (never mind it being unconstitutional), there's a pretty solid chance he'd win. His party still backs him 100%, and nobody has any idea whether they'll maintain control of Congress after the midterms, because they still have enough support to plausibly keep their majority.

It's not about being too meek to fix things. It's about half the country wanting what's happening.
