Nice to term separatists as Terrorists. Uyghurs' have always wanted self-determination and are culturally different from the Han Chinese, hence the resettled Hans in Xinjiang to prevent ethnic homogenity in the region.
Their are a fair few cultural differences in China (even just within the "han race" let alone the other "races"[0].
But I often play the thought experiment in my head: How would the US govt react to the Latinos or the African Americans wishing to create a seperate state within the US?
I don't really see it playing out that differently to what China are doing.
Is this just a case of "China has a problem that we (the US) don't, and look at them struggle with it!" kind of thing?
The US period of herding minorities into sub-states called "reservations" ended a long time ago.
