The US is definetely guilty of genocides. Turkey is a good strategic partner for China to have as it has huge influence on the Islamic world.
However, China must be very careful of Erdogan, he is a total snake. Never show him your back or he will backstab you on the first chance
No other country is guilt of actual genocides EXCEPT the US. For all this blah blah blah, last time I checked there was a country called Armenia for the Armenians, Israel for the jewish... Is there a country called the Iroquois confederacy, the Navajo nation, the Cree nation?
