Pacific War dwarfed the Europe War in logistical terms.
US won 2 wars on broad fronts -while the Soviets prevailed on one front with a lot of help..............................
The US won the Pacific
The Soviets beat the Nazis
The Soviets beat the Nazi's becaue the US gave them more supplies than they could provide for themselves when it was the most critical. Had it not been for the support of the US and the UK during the initial onslaught of Barbarossa and into the beginning of Operation Typhoon the Germans would have won.
After the front was stabilized the continuing support of the western allies made it possible for the Soviets to grind the Germans down while they rebuilt their industrial capacity in the Urals far from German attack, once again making it possible for the Soviets to prevail during that critical time.
And don't ever forget the thousands of American Merchant Seamen who died getting those supplies to the Soviets. Those men KNEW they had a better chance of not coming home than a Marine fighting in the Pacific did and still they went.
The US produced more of everything then the entire rest of the world did and got it to those who needed it most.
