George W. Bush, America's 43rd President (2001-2009), was transformed into a wartime President in the aftermath of the airborne terrorist attacks on September 11, 2001. The attacks on the World Trade Center and the Pentagon changed the course of his presidency and defined his legacy.
Under President Bush's leadership, the United States launched the war on terror, with a primary focus on combating Al-Qaeda and removing the Taliban regime in Afghanistan. The invasion of Iraq in 2003, based on the belief that Saddam Hussein possessed weapons of mass destruction, also became a defining moment of his presidency.
One of the key aspects of President Bush's national security policy was the establishment of the Department of Homeland Security in 2002. This new department aimed to coordinate and strengthen the country's efforts to prevent future terrorist attacks on American soil.
