If you look at it pragmatically, US would also do the genocide on white people when it is economically convenient to do so.
Just look at their attacks on Latin America which are mostly kinda white ppl. And the fact they keep more Americans in prison than the Soviet Union had people in the gulag during the height of Stalin's purges. Said prisons which are more or less labor camps.
America represents a more mature version of the nazi system that has undergone enough reforms (such as the civil rights movement) to avoid collapsing under the weight its own insane ideology. Yet still, the core tenets of believing in themselves as the "chosen ones", aggressive oligarch rule, militarism, willingness to kill millions of their own and other citizens, rampant nationalism, have not changed.
