To be honest the chinese even study its raise up and have a long tv series about it — war is inevitable. Hence the peaceful raise of china is the slogan. They know you do not. Nearly 20 years of sending in students, researchers, 1000 person scheme etc. They win if it is not Xi, you may not even know until too late.

Probably not. The British century was built on the back of dead Germans and Russians containing Napoleonic France. The American century was built on the back of dead Russians and Western European ruins by Nazi Germany. If the third time's the charm, then the next Hegemon would be the faction that successfully minimise its own losses in a WW3, so either India or Europe(an Union).

Then again, history doesn't repeat, it rhymes.
