I’m not sure what language the song you shared is, but the original “Sacred War” is a Russian language WW2 song: https://youtu.be/TSDr8Xxd5h0?si=B8LbYsIV9OEy0hpI

(Edit) I hear “fascist” in the first verse so pretty sure whatever language that is, it’s a direct translation of the Russian original.

I found a YouTube link in your post. Here are links to the same video on alternative frontends that protect your privacy:
