It was formulated an hour after the Infamy Speech of President Franklin D. Roosevelt. Japan had sent a message to their embassy in Washington, but because of problems in decoding and typing out the very long message – the high-security level assigned to the declaration meant that only personnel with very high clearances could decode it, which slowed the process – it was not delivered to the U.S. Secretary of State until after the Pearl Harbor attack. Following the U.S. declaration, Japan's allies, Germany and Italy, declared war on the United States, bringing the United States fully into World War II.
