Not yet, but its hegemony is definitely weakening. No one else is there to step up either. Russia has had its set backs in Ukraine and Syria. China is suffering from an economic bubble of its own and soon will have a declining population. India will be fucked by climate change sooner rather than later. Europe is mostly a threat to itself and migrants.

Anyways rightoids today are much too clownish to run a hegemony properly. Like Elon thinks developmental aid to neighbors of China from the US is DEI and not hegemonic bribes.
