Russia Ukraine war, page-27563

I doubt the 'interviews' are with genuine Ukrainian troops, they will be yet more staged videos by the Russian propagandists. I also doubt the Ukrainian casualties are anywhere near as high as what you are quoting.
I could go on in the same vein but its pretty pointless. You are under instruction to keep repeating falsehoods but the actual situation on the ground, where Ukraine has driven the Russian away from Kyiv and now Kharkiv, gives the lie to the things you are stating.
