The US is that strong, provided they don't have to fight in or near China or Russia. No one besides those three even has a seat at the table. China and Russia could probably defend their own territories, but projecting power is an entirely different can of worms.
> But they would fight in or near China or Russia — I don't see any chinese or russian bases in Canada or Mexico.
Sure. Because they know their limits.
But in the context of the thread, the point is that the US can institute whatever "international law" it sees fit (as long as it as the strength of will to do so) outside of the spheres of influence of China and Russia.
(I think we're heading for the classical Oceania/Eurasia/Eastasia split, but I could have read too many entirely fictional books in my formative years. Personally, I'd have preferred to have been in the timeline with centrifugal bumble-puppy and feelies)
