9-11 has been called "America's second Pearl Harbor," and was even more deadly than the Japanese attack on December 7, 1941 - 2,388 people died in Hawaii that day (1,998 Navy, 233 Army, 109 Marines, and 48 Civilians). The 9-11 attacks caused President George W. Bush's to declare War on terror and sent the United States to war in Iraq and Afghanistan.
Like Pearl Harbor, the 9-11 attacks were surprise attacks without a declaration of war, but unlike the attack that ignited America's entry into World War II, it was not on assault by a nation's armed forces, but one by 19 Muslim men (lead by Mohamed Atta) whose allegiance was to a Middle East terrorist organization called al-Qaeda.
