I wonder if it's in the interests of the United States to have these international students studying here. If they are unable to contribute to the academic debate in any way besides maintaining the CCP line of genocide denial, should their visas be revoked? Would such an action by the federal government be in violation of the 1st Amendment? It may seem like an extreme suggestion, but surely a group of international students that engaged in Holocaust denial in Germany would be on the next flight home.
