Actually, I think it was the American GI and an M1 rifle, along with his sister Rosie the riveter that saved the world....
true- but during the period covered by this movie, FDR had US on the sidelines, even turning Churchill down when he requested help. with the fall of much of Europe around him and no US aid Churchill stood starkly alone on the world stage.
Your are correct. However, would not sell short the Russian peasant with a PPSH.
Bingo! Churchill stood alone against the threat, but the US saved civilization.
