At least China has the intelligence to lock them up.In my opinion, it would be better if they were expelled, but at least they are locked up and not running around blowing people up and cutting their heads off.
Expelled from their own country, the large semi-arid nation state of Xinjiang where they were living peacefully for hundreds of years before China annexed them in 1949? The Chinese did the same with Tibet in 1951 and proceeded to enslave and murder hundreds of thousands, but the rest of the world was far too busy with other things to bother with a nation which most folks wouldn't be able to find on a map?
And the Chinese are still doing it. They forced Tajikistan to cede hundreds of square miles of their nation or face an invasion as recently as 2011. And of course, they are doing the same in the South China Sea, taking shoals and islands by force, calling them ancestral lands.
We or our children or grandchildren will be fighting a war with China eventually. They have had their own way in Central Asia for so long that they think (and they may ultimately be right) that they can do anything to anyone.
