The United States responded to the events of September 11, 2001, by launching a military campaign against the perpetrators of the attacks, Al-Qaeda, and their Taliban hosts in Afghanistan. This campaign, known as the War on Terror, aimed to dismantle terrorist networks and prevent future attacks on U.S. soil. The U.S. also implemented a range of security measures, including the creation of the Department of Homeland Security and the implementation of the Patriot Act, to enhance national security and prevent further attacks. Additionally, the U.S. led a coalition of international partners in efforts to combat terrorism globally and address the root causes of extremism.
