Okay this is some amusing and problematic cognitive dissonance.
The West gets attacked because of its military occupations in Mesopotamia. That is the criteria for Jihad. Any random teenage edgelord that happens to be Muslim can always take the pedantic “its my duty” approach at any time. The vast majority do not, any slight provocation from then on encourages that sentiment. China’s approach avoids this because they have no military occupation of traditionally muslim lands. That approach has worked better for China’s national security while operating in islamic areas, they invest and have been masterful at it. The Western/US approach never factored in its own national security, or any attempt at understanding Islam, and its been a disaster for its people and a boon to its defense contractors. The key point is that its never been about “rising up on behalf of all muslims being oppressed” its always been about “excising a cancer from traditionally islamic lands”. And that makes inaction towards Xinjiang and the plight of the Uighurs make way more sense, than the fundamentally rocky assumption that action from some unspecified Muslim people is expected to occur.
Secondly, some Uighars have already done the terror attacks within China, over “small things”. Long before the massive dragnet and crackdown. This is where China’s identity politics come into play, that some other commenters have pointed out. China’s domestic stance and behavior isn't really about Muslims, its about “territorial unity” with an undercurrent of ethnic discrimination. But ultimately the Uighers are on their own, and East Turkistan isn't going to be a thing.
