There was a lot more fighting on the eastern front.
Indeed. D-Day should have been postponed one year to give the Nazis and Communists more time to kill each other.
True, there was more fighting on the Eastern Front...but without Western and especially American material aid, and without about 80% of Luftwaffe resources being siphoned off to deal with the Anglo-American bombing campaign, Germany almost certainly wins on the Eastern Front.
The 66 German divisions devoted to fighting the Anglo-American armies in North Africa and Western Europe as well as the 7,000 Flak 88 anti aircraft/anti tank guns devoted to defending against Western AirPower were also a massive drain on resources - not to mention the bomb damage done to Germany.
Russia was also a much bigger country, the size of Russia was more than the other territories the Nazis occupied combined.
Without Russia in the War Hitler would have controlled the European continent for many more years.
Without America, Russia would not have been able to sustain a War with Germany.
With America and Russia fighting the same foe, Germany was doomed.
70% of trucks and most of the ammo provided to the USSR during war by America. Plus food. Without it...?
Russia destroyed the Nazis, The Americans and the British Empire stopped the Communists completely taking over the continent. That was our contribution to Europe’s freedom.
And without America pouring arms and food into the Soviet Union, the Nazis would probably have overrun the Soviets in short order.
