Last WWII hypothetical, I promise. For a while, at least.
In 1950 Churchill wrote;
- "No American will think it wrong of me if I proclaim that to have the United States at our side was to me the greatest joy. I could not foretell the course of events. I do not pretend to have measured accurately the martial might of Japan, but now at this very moment I knew the United States was in the war, up to the neck and in to the death. So we had won after all! … Hitler’s fate was sealed. Mussolini’s fate was sealed. As for the Japanese, they would be ground to powder. "*
Let’s say that during an Imperial Conference the Emperor’s verse has more of an effect on Nagano than it did in history. The Japanese rethink the entire attack, thinking more of the strategic disadvantages than their ‘decisive battle’ doctrine. Don’t argue, they just do.
So, Pearl Harbour remains unmolested in December 1941. Without the attack, when would Roosevelt be able to get America into the war? Would he even have been able to, having said in the 1940 campaign;*
“I have said this before, but I shall say it again and again and again; your boys are not going to be sent into any foreign wars.” *
