They never had an Empire as the Soviet Union.
But they did. That’s why Mao called them social imperialists.
As for NATO, it’s to ensure western imperialism stays intact. The US is the main beneficiary, but western Europe participates because they also profit from brutal exploitation of the global south.
That just brings into question how NATO is a threat to Russia then? The only way that would be true is that either a) Russia sees them as imperialist competition, or b) the threat is that Russia can’t attack its neighbors without retribution.
Well, the guy is technically right that the gas chambers in Auschwitz today are fake - because they are replicas. None of the original chambers and crematories survived the liberation of the camp, so they were rebuilt for the museum based on the designs and blueprints the nazis had in their extensive document archive.
