Cope. But......
TBH, while China's rise might be less than ideal (the way they treat animals freaks me the fuck out, for example), a Chinese led world will be better in some aspects. For starters, they tend to be non-interventionist and, unlike the US, they don't place conditions on the poorer countries they trade with (i.e. they sell weapons to African countries and don't give a fuck what they do with them).
If China becomes the world leader, I can imagine:
- Israel won't have a big brother to help them out and they'll need to deal with their aggressive sandnigger neighbors on their own; China is not a Judeochristian society and don't have this nonsense of feeling obligated to support Israel. Also, China has more incentive to side with oil producing Arab countries
- Almost always, weaker societies try to model themselves after the top dog country, and accommodate their laws and values to fit them (mostly) -- China is a society where nerds are appreciated and criminals are rarely romanticized. Films about faggots and dykes are banned. If the world follows China's lead, these things would become the norm
