Oh man, that was a good laugh! I’d consider Ukraine more with us on the military might considering the ass they’re kicking. Switzerland can match us on the gold/economic, but I’m not sure how confident I’d be it isn’t stolen, nazi, or Russian (but I can’t say the same about the US’ either). China will probably come close to matching our military might if only because of their population advantage. India is going to be a massive player here shortly (militarily speaking), if not already.

The problem, and I know it’s what people don’t like to hear, is that the US quite literally cannot be beaten economically or militarily. Seriously, read that article I linked, it’s incredible the economic output the US generates. France has the same economy size as Idaho, a state famous for its potatoes and nothing else.

The best military logistics in the world and logistics is what wins wars. The biggest and most powerful economy in the world, even China and Germany have a stuttering economy (and pre-covid I would have pegged them as being on par). The biggest influence regarding culture, the next closest would maybe be Britain, but when it’s English media the US will still dominate. China has some cultural sway, but only within their own borders and even they consume American media like crazy.

It’s hard to say who out there could play a role in being as powerful as the US, and an empire decline is bound to happen. It’s not immune.

I would however put the early Soviet Union for sure up there with the US. They had some amazing technological innovations. The only problem was that a communist government got into an economic war with a capitalist government and that was never going to work well. Slow and steady growth like the Cubans is more the way to do it.
