> It’s been Russia and China for like 100 years.

It hasn't been. The US was one of the key players who built China up to what it is today, for a significant chunk of the past century they were strategic partners against Russia.

And it is worth remembering that post WWII the US was busy marginalising the Europeans, making sure Germany was prosperous but didn't execute an independent military resurgence and helpfully euthanising the British empire. There were enemies other than Russia and China over that period. It just happens that the other European powers were broken to the point where their resistance was ineffectual and the process was mostly amicable - if they'd been more competent it'd have been a lot nastier.
