The US is treating everyone else like shit and isolating themselves from the world.
The world is slowly esponding accordingly and reconfiguring to the new reality where the US is unreliable and unfriendly.
While it's a lose/lose this will ultimately hurt the US more than everyone else.
The world isn't going to come to the aid of the US and prop them back up to their place of hegemony when this all goes to shit. The rest of the world is going to pick at the carcass of what was once an inspirational empire.
