The Longest Night in Shanghai () is a 2007 film produced by Japan's Movie Eye Entertainment and directed by Chinese director Zhang Yibai. It is a rare collaboration between China and Japan. [SEP] Knowledge 3: United States declaration of war on Japan
On December 8, 1941, the United States Congress declared war (Public Law 77 - 328, 55 STAT 795) on the Empire of Japan in response to that country's surprise attack on Pearl Harbor the prior day. It was formulated an hour after the Infamy Speech of US President Franklin D. Roosevelt. Japan had sent a message for the United States to its embassy in Washington earlier, but because of problems at the embassy in decoding 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 down 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.

The last time the United States declared war on any nation was in 1942, when war was declared against Axis - allied Hungary, Bulgaria, and Romania, because President Franklin Roosevelt thought it was improper to engage in hostilities against a country without a declaration of war. Since then, every American president has used military force without a declaration of war.

Answer: December 8, 1941
