The 9/11 attacks were the deadliest terrorist attack in world history. On September 11, 2001, 19 al-Qaeda terrorists hijacked four passenger planes and used them to attack the World Trade Center in New York City and the Pentagon in Arlington, Virginia. The attacks killed 2,996 people, including the 19 hijackers.
In the aftermath of the attacks, the United States launched the War on Terror. The War on Terror has resulted in thousands of innocent civilians being killed by drone strikes in countries such as Pakistan and Yemen. It also cost trillions of dollars, which could have been spent on other things like education or infrastructure development instead.
The 9/11 attacks continue to shape American foreign policy today. For example: America’s military response to 9/11 led to drone strikes killing thousands of innocent civilians in countries such as Pakistan and Yemen–and those drone strikes are still happening today!
The 9/11 attacks have had a profound impact on the world as well; they inspired other countries around the world to create their own versions of these kinds of attacks in order to cause fear among their own citizens.
