This made me laugh. The American warplan for an apocalyptic war with the British Empire in the 1930s. Best documentary ever!!!

Who do you think would have won
I think Britain, but at the loss of Canada perhaps, the British fleet was simply too big and would have destroyed the US fleet and begun shelling East Coast cities, forcing them to capitulate. Although Britain really didn't have the resolve for such a war (Concerns elsewhere), it could have gone that way.
