Maybe if Trump's first term was the end of it. But by reelecting him and more notably every supposed check and balance failing, the US has proven it can't be trusted not to elect another destructive idiot again in another 4 years. Also, they know Trump is a demented old fool, he's not the one coming up with the major steps to tear down this country. This is what the people controlling the GOP want ... all laid out in Project 2025.
It will take decades to get back to where we were even if we managed to never hand power to the right again. Which is unlikely to happen because people are so goddamn stupid, hateful, and brainwashed. And the Democrats are controlled by people who outright prefer Republicans to the kind of leadership we'd need to even begin repairing the damage.
