How about if we do the courageous thing and give them war till they stop?

We are morally no different than Europe prior to Hitler's invasion; knowingly allowing the genocide of others as long as it didn't affect us.

Cute thought but it's never going to happen. Hitler was a moron who kept prodding the Allies with invasions that were creeping ever closer West. At that point, the third Reich had become an existential threat to the Allies. They would have never went to war over the plight of some Jews and other hated minorities.

China on the other hand manufactures much of the world's consumer goods and has strong trade ties with dozens of nations. It has also never invaded Europe and shows no sign of having any intention of doing so. It also has a large enough army and nuclear armament to completely flatten any European country that chooses to break from NATO and try to pick a fight with it by itself.

NATO nations sell arms and political support to countries like Saudi Arabia and Israel so clearly morality is not a priority here. The real reason why they keep political pressure on China is because it's a rival to the USA and it's (at least in it's own eyes) communist - which is worse than stoning women and gay people to death, and bombing children hospitals and practising apartheid in the eyes of Washington D.C.
