Well if an army is getting armed and trained by NATO but still lost to opponent that they are absolutely convinced to be inferior, something must be not quite right. Therefore the “asiatic horde human waves” are invented, but this can’t be the only reason, since all the NATO training and weapons are precisely made for that, as all western war movies taught them. So of course it’s the fault of the “subhuman Slavs” who simply cannot understand how to use them.
