Yes, but they didn't enter out of a sense of duty or morals is my point. It is the most significant event of the last century and they opted to stay out of it until it affected them ..it goes against the narrative of the USA being a defendor of the world order and a moral authority.

Stalingrad was less about Russia, more about Hitlers hubris and general winter. Similar to what the USA is finding out now. Some terrains and territory is harder to attack successfully.
