Pearl Harbor on attack

On December 7, 1941, the Japanese army attacked the American fleet at Pearl Harbor in Hawaii. In total, 2, 4000 Americans were killed and hundreds injured. There are also the destruction of 188 planes and 3 American ships. Eleven boats and about 130 aircraft suffered damage. This attack led to the entry of the United States into World War II. President Franklin D. Roosevelt, on December 11, 1941, declares war on Japan.Several decades after Pearl Harbor, the debate is still open on the veracity of the facts of the attack. Did US naval radar in the Pacific had detected the Japanese naval armada prior to the attack; and American commanders at Hawaii had chosen to suffer the attack and push the United States into World War II? Did Pearl Harbor was indeed a surprise attack and must be regarded as President Roosevelt described it as ＂a day ofinfamy＂?
