Any way you slice it, this invasion has been a debacle for the Russians. The US was in Vietnam (in large numbers) for about a decade and lost just over 58,000 soldiers. By contrast the Russians, who have only been in the Ukraine since February, have already lost 50,000 soldiers. It's not exactly Stalingrad level, but it's still pretty fucking bad and demonstrates two things: one, that the Russian armed forces are really, really bad at doing army stuff, and second, that the people in charge of all those Russian soldiers have demonstrated that they really don't give a shit how many of them have to die. There seems to be no effort being made to do anything other than send more bodies into the meat grinder. Eventually, those foot soldiers are going to catch on to this (if they haven't already) and the whole thing is going to collapse.
