We have mountains of literature, including by US intelligence couching it in euphemisms, saying basically that about the Middle East and the US. Just think Gitmo. I remember hearing the "argument" a lot, where people admitting that some people in Gitmo might be innocent, but by now have been treated so badly, they can't be released because they'd try to harm the US for sure.
'US intelligence' is a bit of an oxymoron, TBH. Weren't they going to bring democracy to Iraq? That has gone well for sure. If we really want to keep a constructive attitude towards the Middle East, it's important to keep that goal in mind and stick to it, without pursuing distractions. What the Chinese seem to be attempting is an obvious non-starter for lots of reasons.
On top of that, it probably doesn't even work. Time will tell. However the Uighyers felt about the Chinese before, now they will harbor a white-hot rage. This entire generation of adults can never be trusted by the Chinese, they will have to imprison them forever or kill them. That's basically genocide. Yes if you kill or lock all the people up there will be no more problems. Is that really a good solution? And if the boot ever gets removed from their neck, and they get a chance, they will fight back. Misery upon misery.
