"a unipolar world" that benefits you is a good thing, I get it. But that kind of thinking is the reason why the US isn't very popular on the world stage, even with its allies. Most of them would backstab the US if they could afford it. Thankfully, politics is a coward's game, keeping everyone a little bit more alive unless your ambitions are absurdly grand.
The US is not very popular anymore because it kept abusing it's unique position as the #1 military power, starting wars it had no business starting, not because it is(was?) #1 as you are suggesting.
Versus China (annexed Tibet), Russia (annexing Ukraine) and Iran (banana republics across the Middle East)?
People like to see themselves as edgy. It's edgy to be in the rich world and decry imperialism of America's system of allies.
