Before 1941, the united states was still sending shipments of Petroleum to japan.
Why did japan attack the United States in 1941 ?
Japan planned the assault as a preventative measure. Its goal was to stop the US Pacific Fleet from interfering with its planned military operations in Southeast Asia against the US, the UK, and the Netherlands' overseas possessions.
Japan intended to create its own empire and had been modernizing its economy for much of the 20th century. However, with all but 6% of its oil supply imported, Japan lacks the natural resources to make it a reality.
In retaliation for the Japanese occupation of French Indo-China, President Franklin D. Roosevelt confiscates all Japanese assets in the United States on July 26, 1941.
