I mean your a leftist, you don't love America, not even the idea of America, that's simply why most leftists start being leftists, from there they go to all sorts of strange places to fit their outgroup love.
the Rest of the World cannot alienate from us, they have NO CAPACITY to do so, because it revolves around us, by our dollar, or by our violence, and alot of the time, both.
We are more powerful and influential than Rome ever could have dreamed to be, even with all or politicians being fuckups, you couldn't just "Alienate" yourself from Rome, and you sure as fuck can't do it here, the only other games in town are China, and fucking RUSSIA, who's GDP is smaller than Texas, there's no one to go to, and I promise, if anyone even thinks of trying to be the next Go To, we'll fucking kill them.
your another End of History type, where you don't realize that all dealings with other "tribes", Nations or what have you, are always the same, we can trade, or we can take, and when you are in the super position, you then can DECIDE to trade and not to take, and that's where we are, nothing is going to change this for decades.
