What if America had threatened to cut off aid to England in 1941 unless England stopped retaliating against Germany?
England would be a part of the Third Reich right now.
Papa Joe Kennedy would have loved that.
It is, and always has been.
Actually, it wouldn’t have. Germany couldn’t conquer Britain, albeit we couldn’t conquer Germany and W Europe/Europe without American, Canadian and Empire help and resources.
No America 1941-45 would have meant a stalemate.
