uh, in WW 1, there were no “Soviets” - to equate beating Tsarist Russia in WW 1 with beaing the Soviets in WW 2 is not a valid comparison. The Soviet Union was established in 1922, tho the communist revolution happened in 1917.
I understand your point, but Tsarist Russia never surrendered in WWI. Lenin was sent in to do just that. The comparison is close enough; incompetence from the top, a repressive government squandering lives without conscience, bolstered by foreign aid from western allies - yes, close enough.
