Governments will change, people on the top might change. The question is whether they will face any consequences for their actions. Will the US as a whole face any consequence of its actions. Like the consequences other countries face when they do the stuff America is doing right now.
Or will it be back to normal as soon as the regime changes.
Will there be any lasting effects in how the world deals with US?
Maybe politically they will somehow fix some of their relations with the rest of tde world if they elect a sane president (maybe). However, the fact remains: they elected a clown twice and there’s a huge portion of them willing to elect him again. The damage is done and even if they repair their relations, it won’t be the same.
Socially on the other hand? Yeah, they are done for. People are done with usian culture and their influence is fading rapidly. People don’t want usian products, and the want to be further from them, not closer. The US have lost their status as the “beacon of the western world”.
