The most devastating terrorist acts in American History took place on September 11, 2001 as the World Trade Center towers were leveled. Nearly 3,000 people were killed. These attacks were carried out by al-Qaeda under the command of Osama bin Laden.
Messages made public to Americans, by bin Laden, praised the attacks on the U.S. however; denied any involvement. Bin Laden legitimized the attacks by identifying grievances felt by both mainstream and Islamist Muslims, such as the general perception that the United States was actively dominating Muslims. He then claimed the attacks were not targeted toward women and children, rather the American icons of military and economic power.
Since 9/11, evidence has proven that the original attacks were targeted at nuclear power stations on the east coast of the United States. The targets were later changed by al-Qaeda as the U.S. retaliation was welcomed.
