Terrorism can impact nations globally and locally. International terrorism involves violent and criminal acts by individuals or groups linked to foreign terrorist organizations or state-sponsored entities. The Federal Bureau of Investigation (FBI) states this definition clearly on their website.

Meanwhile, domestic terrorism includes violent and criminal acts aimed at furthering ideological objectives arising from internal factors. These may involve political, religious, social, racial, or environmental influences.

The FBI plays a central role in investigating and preventing terrorism, both on an international and domestic front. Prominent foreign terrorist organizations identified by the U.S. government include Al-Qaeda, ISIS, Hamas, and the Taliban.

September 11, 2001, marks a somber chapter in U.S. history. This day saw the destruction of the Twin Towers in New York City following their collision with commercial airplanes. Another plane struck the Pentagon, and a fourth plane crashed in Pennsylvania. Al-Qaeda, under the leadership of Osama bin Laden, orchestrated these attacks.

Years later, in May 2011, Navy SEALs located and killed Osama bin Laden. At that time, Barack Obama served as the Commander-in-Chief.
