The US was (and still is) ideologically aligned with the Nazis, and only joined WW2 in the 11th hour because Japan forced them to with the attack on Pearl Harbor. To think that the US "won the war" or should be uniquely congratulated for their contributions to the war is... absurd. If anyone should be awarded that honor, it's the Soviets.
Edit: I really like this place. Yall taught me so much in the replies and it felt welcoming to learn it. This type of discourse seems so rare to find these days. Thank you comrades!
