I saw some very uninformed statements about role of the USSR in the WWII. Please people, get some real, academically sound books, read memoirs of Soviet and German generals, look at statistics before making a fool out yourself by asserting that USSR just "helped" to win WWII.
Just a small example that illustrates who really defeated nazi beasts and the attitude of the opposing forces. Wenck's 12th army and the remnants of the German 9th army (destroyed by Red Army) were senselessly fighting advancing Red Army just to surrender to American forces. German guns continued to fire on advancing Red Army troops and Americans on the other side of Elba river watched and did nothing! Majority of German POWs on that day hoped and believed that Americans are going to join with Germans to drive out invading Soviet Army. Until allied invasion in 1944, more the 90% of Wehrmacht's best troops and best equipment were engaged in the Eastern front as most of the Romanian, Finnish and Hungarian armed forces. Italians had a contingent in USSR that was larger than their Afrika Corp. There was a Spannish "Blue Division", French LVB and later SS Charlemagne division (last defenders of Reichstag), Lithuanian, Estonian, Latvian SS divisions, Belgian, Dutch - Nordland and Viking SS Divisions, etc, etc.
Yes, America helped to win the war, but majority of this help was through land lease of gunpowder, great Studebaker trucks (2/3 of trucks in Soviet Tank Armies), portable radio sets, air cobras
