How did the 9/11 attacks impact the world?

The terrorist attacks of September 11, 2001, commonly referred to as 9/11, had a profound impact on the world. The attacks were carried out by al-Qaeda terrorists who hijacked four commercial airplanes and flew them into the World Trade Center towers in New York City and the Pentagon in Washington D.C. Another plane was headed for a target in Washington D.C. but crashed in Pennsylvania after passengers attempted to retake control of the plane from the hijackers.

The attacks caused the deaths of nearly 3,000 people, injured thousands more, and caused significant economic and political upheaval. In response, the United States launched a War on Terror, invading Afghanistan to oust the Taliban regime and hunt down al-Qaeda operatives. The war would later expand to include the invasion of Iraq.

The attacks also had a profound impact on international relations and global politics. The U.S. government's response to the attacks, including the War on Terror and the passage of the Patriot Act, sparked debates about civil liberties, surveillance, and the use of military force. The attacks also led to increased security measures and changes in airport security protocols that remain in place today.
