The Attack on Pearl Harbor was a surprise aerial attack largely on Pearl Harbor, Oʻahu, Hawaiʻi, and the USA launched by the 1st Air Fleet of the Imperial Japanese Navy of the task force Carrier Striking Task Force  on the morning of Sunday, December 7, 1941 (Hawaiʻi time).
It was aimed at the Pacific Fleet of the United States Navy and its defending Army Air Corps and Marine defensive squadrons as preemptive war intended to neutralize the American forces in the Pacific in an impending World War II. Pearl Harbor was actually only one of a number of military and naval installations which were attacked, including those on the other side of the island.

Pearl Harbour var USA’s ulykke men Europas lykke – USA gik med i 2. Verdenskrig. Resultatet kender vi. Hvis det ikke var sket , var vi måske under nazistisk herredømme idag? Tak USA.
