It might be argued that the relative peace in Europe and Asia is already cracking up, given the ongoing war in Ukraine.
Either way the world is a completely different place than it was in 1949 or 1989, and as the global situation evolves it makes absolute sense to adapt with it.
like imagine at some point roman empire and china is co-exist together and 2000 years later only 1 survive
I think one possible reason is that the Qin Dynasty really managed to assimilate everyone into the same shared values, religion, language, writing, and so on. Other empires didn't succeed to that level, and the people in them always had strong differences, language, values, religion, beliefs, writing, philosophy, and so on.
It sounds like a joke but that is exactly how it works and many people have forgotten it.
