Who was the U.S. President during the September 11 attacks?

The U.S. President during the September 11 attacks in 2001 was George W. Bush. He was in office during this significant event in American history, which included coordinated terrorist attacks on the World Trade Center in New York City and the Pentagon.

Under Bush's leadership, national security and foreign policy were profoundly affected by the attacks, leading to the War on Terror and the subsequent invasions of Afghanistan and Iraq. His administration's response to the attacks shaped domestic and international policies for years to come. The moment of the attacks and the immediate actions taken by his administration have remained pivotal in understanding post-9/11 America.

In contrast, the other presidents listed were in office during different time periods that do not relate to the September 11 attacks. Bill Clinton served as president from 1993 to 2001, Barack Obama took office in 2009, and Ronald Reagan served from 1981 to 1989. None had a direct role in the events occurring during 2001.
