I think it's important to have an ice cool perspective on ww2.
Look at the numbers, look at numbers relative to population, look at aggressors, look at the amount of "freedom" that was won in the aftermath.
There's no doubt that both russian and western perspectives are twisted in their own favour, but if you are willing to read up on things all the information is there. For example, the brunt of the war took place in Eastern Europe, there's just no denying that. What the western powers did was peanuts in comparison to the horror and sacrifices on the eastern front. One can even see the opening of the western front almost as mopping up to make sure the red army didn't "liberate" all of Europe, since the german forces were already on the retreat by that point.
(Churchill suggested to beat the red army with nukes after the war was over..)
Anyway, as history shows, the "liberation" provided by the red army in most countries turned out to be less of a liberation, and more like a new kind of occupation.
What's more interesting though, is how the 2nd world war is
used today for propaganda purposes. There's no doubt the russian narrative is still one of the least modern perspectives. And not very balanced or complete. Little has changed..
