The "Russian Human Wave" narrative is based on Nazi propaganda from World War II, trying to draw a racist connection between the asiatic Russians and the Mongols, the idea of the "Mongol Horde." Neither the Red Army during World War II nor the modern Russian Federation use human wave tactics, the closest was the Tsarist army pre-Socialism.

Further, Russia is not trying to endlessly expand, they are trying to fully de-millitarize Ukraine as Ukraine was cozying up to NATO, and NATO promised long ago that it wouldn't expand eastward yet it has consistently done so over the last few decades, forming millitant encirclement of Russia by hostile countries that want Russia to open up its capital markets for foreign plundering. Further, the nationalist government of Ukraine was shelling ethnic Russians in Donetsk and Luhansk, both of which declared independence from Ukraine before Russia invaded.

Regardless of the morality of Russia going to war with Ukraine, there is no evidence that the RF is seeking to expand westward. This is just Red Scare 2.0 nonsense.
