Yeah...the problem is that if you want to keep the moral high ground you need to abide by the rules, if your military tradition already is lousy (russian) then you don't care and can just ignore all the rules, it's shitty but what can you do? Lowering ourselves to their standards isn't an option.
After the war russia should be very contrite and humble, and friggign teach their history for once. WWII didn't start in 1941 you absolute basterds. (conveniently AFTER the Winter War and the invasion of Poland...)
