Will the country ever unite again, or are we destined to a divided America and will go the way of the Roman Empire?

Well, Biden is trying to undo 4 years of Trump’s chaos, which is what he promised. If he’d done nothing, he’d be breaking his word to those who voted for him. And the far right was going to fight Biden regardless. They fought the fact that he was legally elected, after all. I don’t see them being willing to work with him, even where it would benefit their constituents. But he has to work for the good of everyone now, even the Trump stragglers.
