It's mostly racism. It plays on their views that non-whites don't care about human life and see everybody as expendable. Only the western civilized white man knows empathy and the value of life or some shit.
I'm afraid it gets even worse. They imagine that every white, Anglo, and Western Christian life is to be cherished. While the lives of the other 'inferior' races are expendable.
We see many Hollywood movies where there were good coloured people vs bad coloured people, and both of them kill each other by the hundreds. Then the white savior comes in, kills hundreds more of the bad coloured people and take few casualties. What few white casualties they took, they were given long sending offs.
Russians and slavs are considered coloured people in the Anglo Saxon mindset. So they are either cannon fodder, or numerous evil grunts to be killed by the civilized Anglo Saxon heroes. Just look at COD's depiction of Soviet WW2 troops, and modern Russian soldiers.
300k American lives were lost in WW2 and they tell so many stories about sacrifice, valor, and honor. The 27million Soviet lives, and 20million Chinese lives that were lost in WW2 are just statistics. Their lives, reduced to just numbers and condemnation of their 'inferior' civilization.
For the Anglo Saxon elites. They enjoy watching two slav brothers, the Ukrainians and Russians butchering each other to death. They don't mind losing 1000 Ukrainians a day just to kill some more Russians. This is depravity. This is as evil as it gets.
