Lukacs, John. "No Pearl Harbor?: FDR Delays the War"
Divergence: 1941 CE
What if: An initiative by Franklin Roosevelt in November 1941 caused the Japanese to call off the attack on Pearl Harbor.
Summary: Short speculation that after a six months delay, Japanese militarists would have gained the upper hand and attacked British possessions. The United States would then have entered the conflict, and the war would have come to a similar conclusion.
