On the morning of Sunday, December 7, 1941, the Imperial Japanese Navy attacked the US naval base at Pearl Harbor (Hawaii).
The Japanese victory was absolute and became the first part of a rapid offensive to seize the Pacific Ocean and its main strategic points.
The idea was to depend less on the United States because it was their oil supplier. The day after the attack, President Franklin Delano Roosevelt announced the entry into the war against Japan and the Second World War.
