But @Luca Chinese "education" camps for Uyghurs and Guantanamo are two different things, not only in terms of size. The purpose for both facilities are also quite different. The Chinese are incarcerating over 1 Mio. people because they are Muslims and not Han Chinese. And forcing people to give up on their culture and religion.
I mean with Guantanamo you could say at least there were national security reasons behind it. I am not trying to defend what happened in Guantanamo, just pointing at the differences.
