This does have the underpinnings of an American hate thread, what with the gross generalization and all. Yet, I can see the OP's motivation behind the thread (or I think I do, at least).
Disclaimer, I'm an American and used to be in the military. I also run in several circles, a large portion of the people in those circles don't have any advanced schooling, relying mostly on what public education can bestow and what movies have undoubtedly re-focused.
I do believe that Americans' opinion of their influence, or more importantly the downplaying of other countries' sacrifices, is exaggerated. Yes, the US was a huge influence in terms of resources and manpower, and I wonder if the Russians would have been able to win a war fought on two large fronts (Germans and Japanese). The Russians were able to kick a ton of ass, but only because the average Russian soldier was as afraid of their own government as they were of the German soldiers. I'm postulating here, but I don't think the Russians could have continued the huge losses indefinitely when coupled with the fear of their own superiors.
Likewise, the French and Brits are often depicted as being rolled over by the Germans. Yes, they were fought off mainland Europe, but they never stopped resisting and fighting in one form or another.
I personally hate the image given to the French soldiers. Any soldier, with the proper leadership, can kick ass. The major problem with the French army, especially around the time of the German invasion, was an abundance of incapable leadership. The fact that the French Resistance never stopped fighting cements in my mind, the steadfastness and undying rebellion that is not only the French people, but of any people who are invaded. History has taught us that any people, when invaded and oppressed, will continue to struggle, no matter the cost.
In general, I think the OP's message was lost in generalizing all Americans as uneducated or without world view.
