How did the u. s respond to the terrorist attacks of 9-11

In the aftermath of the attacks, many U.S. citizens held the view that the attacks had "changed the world forever." The Bush administration announced a war on terrorism, with the goal of bringing Osama bin Laden and al-Qaeda to justice and preventing the emergence of other terrorist networks.

The United States government created the Department of Homeland Security (DHS) in response to the attacks. DHS is a cabinet-level department of the federal government of the United States charged with protecting the territory of the United States from terrorist attacks and responding to natural disasters.

Hope this helps.
