Good points...but I like to think we won because our people believed they were morally justified, and our people at all levels were not afraid of being shot because they disagreed with Roosevelt and our military personnel at all levels were empowered to make decisions. Basically, our way of life was the key to victory.
And, I could not disagree with you more stongly regarding equipment. The Germans did NOT have better rifles. The USA held that distinction (As your namesake so succincly put it) When he stated that the M-1 Garand is the weapon that won the war.
And, I would also disagree they had better planes. They had no match for the Liberator. They had no match for the Fortress. They definitely had no match for the Superfortress. Our fighters were just as good or better, although I concede the FW-190 D-9 was an extraordinary plane, as was the ME-262. Doesn't do you any good if you can't get em in the hands of your pilots and maintain them though, does it?
I will agree completely with on tanks. Germans had the best tanks in the world, hands down.
And with all of that, their leadership failed them. Without appropriate leadership, the most magnificent soldiers are going to lose.
Of course, the Germans never fielded it. They could not.
Not to mention the fruits of John Moses Browning, in all their manifold goodness.

Although it is techically different the concept was used by the Russians to develop their AK 47.
