What did Hitler think about the Japanese surprise attack on Pearl Harbor, Adolf Hitler, the leader of Nazi Germany, was informed about the Japanese plan to attack Pearl Harbor in advance. The attack occurred on December 7, 1941, and Hitler was informed about it shortly before it took place.

Hitler saw it as a positive development for the Axis powers because it meant that Japan, Germany’s ally in the Axis, was taking bold actions against the United States.

Hitler believed that Japan’s attack on Pearl Harbor would divert the attention and resources of the United States away from the European theater, where Germany was engaged in warfare. He hoped that this would make it easier for Germany to achieve its military objectives without the interference of the powerful American military.

However, the attack on Pearl Harbor ultimately led to the United States entering World War II on the side of the Allies, significantly altering the dynamics of the conflict.
