As a American myself (que impending hate after this post), I think we were monumental to the success of the Allied Operations. I think it is for reasons that many overlook or simply don't know about.
Before we entered the war, we through the lend-lease act provided arms and raw materials to our both the British and eventually the Soviets. Someone earlier mentioned the victories of the British in North Africa; compared to the Panzer IV, the British Crusader and Matilda tanks weren't exactly all that great. Hell, even the Shermans we supplied to British before the second battle of El-Almein (turning point in North Africa) had a hard time standing up to them. But they needed one heavy tank supplied to them if they wanted to turn Rommel around. The Russians recieved quite a bit in both raw materials and weapons from us as well, as well as some 50 odd destroyers that were useful in the battle for the Atlantic. http://en.wikipedia.org/wiki/Lend-Lease.
The other part that is often overlooked is the Naval Component; from 1940-1941 it was called the "Happy Time" for German U-Boats because of all the havoc they caused. Admiral Karl Donitz of the German Navy started using what was called "wolfpacking" for taking out conveys, which proved to be a highly successful method of commerce raiding for the Germans; by the time the US entered the war the oil levels in Great Britain had reached a critically low point. While the Royal Navy was doing its best to clamp down on it, it simply wasn't big enough to all the German's subs (neither was our own Navy, so it required the both of us), and without raw materials being shipped to the British isles I doubt they could have held out.
Theres more but I am to tired to remember them, so I'll end with this; I in no way trying to downplay the roles of the other Allied Powers during the second World War; we needed you as much as you need us.
TL;DR: You kicked ass, we kicked ass, lets do that again sometime.
