With their current demographics? Doubt it.
At least the US has the benefit of not really having a core ethnic class.
(To stem off the haters, the US has a "massive problem with racism" exactly because we have such a mixed society. Most monoracial places are obscenely and shamelessly racist, but never has a chance to arise)
The Chinese are clearly doing some "rebalancing" lately. Some would even say that "rebalancing" is not a strong enough word. "De-linking" is a word a lot of those people are more comfortable with using to describe what we're seeing.
You can't really have a unipolar power if that power simply "takes all their marbles and goes home" so to speak.
I think we need to really do some strategic planning around scenarios where China or Europe simply withdraws from the rest of the world. Or decides they only need subsaharan Africa for instance.
Or, the nightmare scenario; where China, Europe, and subsaharan Africa actually figure out that together they don't really need anything from the rest of us.
saying unipolar is better is like saying absolute monarchy is better. sure it is, as long as the good king is alive.
