A majority of scholars have rejected the conspiracy theories that Roosevelt, or any other high government officials, knew in advance about the Japanese attack on Pearl Harbor.[274] The Japanese had kept their secrets closely guarded. Senior American officials were aware that war was imminent, but they did not expect an attack on Pearl Harbor.[275] Roosevelt had expected that the Japanese would attack either the Dutch East Indies or Thailand.[276]

In late December 1941, Churchill and Roosevelt met at the Arcadia Conference, which established a joint strategy between the U.S. and Britain.
