What were the reasons behind Japan's decision to attack Pearl Harbor on December 7, 1941?

Japan's Attack on Pearl Harbor

Japan's attack on Pearl Harbor was a retaliation against the United States for cutting off Japan's oil supplies.

The conflict that led to Japan's attack on Pearl Harbor during World War II traces back to Japan's imperial aggression in the 1930s and the subsequent trade restrictions imposed by the United States. Japan's imperial expansion into Manchuria and later into French Indochina resulted in tensions with the United States.

In response to Japan's actions, the United States adopted increasingly severe trade restrictions including freezing Japanese financial assets and imposing an embargo on oil and gasoline shipments to Japan. This economic warfare deeply impacted Japan as the country heavily relied on imported oil to fuel its military and economy.

Viewing the embargo as an act of war, Japan saw the attack on Pearl Harbor as a means of retaliating against the US trade sanctions. By launching a surprise military strike on the naval base in Hawaii, Japan aimed to cripple the US Pacific Fleet and deter American intervention in the region.

Following the devastating attack on Pearl Harbor, the United States declared war on Japan on December 8, 1941, marking the entry of the US into World War II. The events surrounding the attack on Pearl Harbor shaped the course of the war and its aftermath.
