And you seem forget that the reason Hitler did so well at the start of the wart was because of the Molotov - Ribbentrop Pact where the Soviets agreed to let Hitler run roughshod over Western Europe in exchange for control of the portion of Ukraine they did not control  before the war.  Had they not made that agreement, Hitler would have faced a two front war and would not have gotten near as far as he did in the west.

As for Ukraine not existing, I get so tired of you Russians telling this lie over and over and over.  Kiev, the capital of Ukraine, was a well established city by 988, when the king of Ukraine decided to be baptized into Christianity.  At that time the area where Moscow now sits was a swamp with uncivilized humans defending themselves against wolves.  If you Russians want to claim that your country started in Kiev, why do you have your capital in the swamps of the Moskva river instead of a place like Kiev, which has plenty of high ground.
