Terrorist attacks can occur on either an international or domestic scale. The FBI defines international terrorism as violent, criminal acts carried out by individuals or groups inspired by, or linked to, designated foreign terrorist organizations or state sponsors. Domestic terrorism, on the other hand, involves violent acts by individuals or groups driven by ideological goals rooted in political, religious, social, racial, or environmental factors within a country.
The Federal Bureau of Investigation (FBI) serves as the primary agency in charge of investigating and preventing both types of terrorism. Notable foreign terrorist organizations recognized by the U.S. government include Al-Qaeda, ISIS, Hamas, and the Taliban.
September 11, 2001, stands out as a grim day in American history. On this day, the Twin Towers in New York City were destroyed after being hit by commercial airplanes. Another plane crashed into the Pentagon, while a fourth crashed in Pennsylvania. Al-Qaeda orchestrated this attack, led by Osama bin Laden. U.S. Navy SEALs killed bin Laden in May 2011, with Barack Obama serving as Commander-in-Chief at the time.
