There are 11 aircraft carriers in the world that are over 100,000 tons. This includes aircraft carriers that are under construction.
All 11 of those are American. We also have 9 other 40,000 ton carriers. But these don't even get classified as fleet carriers, they're just 'amphibious assault ships', because in any situation where there's a proper battle involving carriers, they're just not going to be necessary.
From an effectiveness point of view, the two most powerful air forces in the world are the USAF, and the US Navy. The F-22 is still unmatched in terms of air to air combat, especially when it is supported by an F-35.
In terms of military strength, US hegemony hasn't gone anywhere, and isn't going anywhere. China may be able to defend itself using anti-ship missiles and air defense systems, but they're not going to be capable of launching an offensive. Russia can't even invade Ukraine, they are a joke. NATO is effectively lead by the US (the Supreme Allied Commander in Europe is a USAF General), and if you compare European militaries to the US, its very one-sided.
While some of the middle east does their own thing, Iraq is still trying to function as a democracy after we installed a government there, SA is still our ally on paper, Israel is still a country, etc, so you can't say that the US doesn't have any influence there.
India is able to ignore the sanctions on Russia, because they are an important ally for the US against China. This doesn't mean they don't need to care what the US thinks, but it does mean that in return for being a strategic ally in the region, they get a lot of leeway in other things they can do.
