> essentially a POW camp
The US government refused to treat people in Guantanamo Bay as POWs. That's why they called them "enemy combatants." POWs have rights.
Guantanamo Bay itself was only a tiny part of the larger War on Terror. The US ran prison camps scattered throughout the world, in which it tortured prisoners. The US kidnapped civilians and flew them to secret prisons, or to be tortured by allied countries like Egypt. One person was even kidnapped by American intelligence off the streets of Milan.
In Iraq, the US worked with Shiite militias that tortured and killed large numbers of people suspected of being sympathetic to the insurgency. The US itself ran prisons like Abu Ghraib, in which prisoners were tortured. Hundreds of thousands of civilians died in Iraq, as a result of the illegal invasion.
No senior figure involved in these crimes was prosecuted.
So when the US government suddenly develops a conscience, consider me skeptical.
Guantanamo Bay and the Xinjiang camps are not comparable. For all its faults, Guantanamo is essentially a POW camp that contains enemy combatants. No American citizens are detained there, and none were ever meant to be.
The Xinjiang camps were specifically built to forcibly indoctrinate civilian ethnic-minority Chinese citizens and suppress their community and culture. They operate on a much larger scale, and also provide a captive labor pool that's being exploited.
