You could argue that China have already won without fighting a single battle. Their strategic currency reserves and holdings could easily topple the US if they liquidated assets overnight with little care for the market; it would be horific as asset prices would explode.
Nope, no need for an armed force; the east has beaten the west as a society and will take its mantle as the global hegemony over the next 2 decades. The best we can hope for is less world policeman and more about shaping the landscape to cope with the lack of resources the scourge of global overpopulation will bring.
The East got our cash, wealth and assets. We got tat in return; cheap TVs, toys and branded consumerist clothing whilst we sold ourselves out to the banks, all the while inept labour government sat back and watched consumer debt spiral to well over 100% GDP over 13 years of complete mismanagement.
We are truly *cked.
