United States marks 25 years since 9/11 attacks as generational memory shifts

Commemorations mark quarter century since 2001 attacks

The United States observes the 25th anniversary of the September 11 terrorist attacks on Friday, marking the deaths of 2,977 recorded victims. President Donald Trump will attend commemoration events at the Pentagon rather than in New York, where hijacked airliners struck the Twin Towers of the World Trade Center. The coordinated assault involved 19 hijackers (15 of whom were from Saudi Arabia) who seized four commercial passenger flights. All four aircraft crashed within 77 minutes across sites in Lower Manhattan, Arlington, Virginia, and Shanksville, Pennsylvania.

On the morning of the strikes, President George W. Bush learned of the second tower collision at 9:03 AM while visiting Emma E. Booker Elementary School in Sarasota, Florida, when Chief of Staff Andrew Card delivered the news. Bush paused for seven minutes before leaving the classroom.

A generation without firsthand recollection

An estimated 100 million people in the United States have no living memory of September 11. For young Americans born after 2000, understanding of the attacks developed through classroom instruction, documentaries, and internet archives rather than lived experience. Tyler Yezermanski, born six months prior to the attacks, subsequently deployed to Afghanistan in 2021 during the final stages of the deployment.

Initial public responses of unity across American communities gradually shifted toward political polarization, expanded domestic surveillance, and heightened anti-Muslim sentiment following the deployment of overseas military operations. Jack Johnson, an Illinois resident born two months before the attacks, reflected on the lasting domestic legacy:

I think that every single political trend in the United States in the 21st century can be traced back to that day.

Milford resident Jennifer Jasensky and Omaha resident Elizabeth Zorko described the intense communal solidarity that immediately followed the tragedy.

I remember meeting the eyes of total strangers and there was a look that wasn't there before, as if a deep personal connection had been forged by this shared horrific experience.

Two decades of military campaigns

The Bush administration initiated military operations in Afghanistan in October 2001, overthrowing the Taliban and dismantling training camps. Anti-Taliban forces took control of al Qaeda positions in the Tora Bora mountains in December 2001. In March 2003, the United States invaded Iraq under allegations concerning weapons of mass destruction.

The deployment in Afghanistan concluded in 2021 as remaining American troops withdrew from Kabul and the Taliban returned to power. Research from the Costs of War Project at Brown University indicates that related military actions across Afghanistan, Iraq, Syria, Yemen, and Pakistan caused approximately 940,000 deaths.

Organizational trajectory of al Qaeda

Al Qaeda was established in the late 1980s by Osama bin Laden during the conflict against Soviet forces in Afghanistan. Bin Laden was stripped of Saudi citizenship in 1994, expelled from Sudan in 1996, and issued declarations of war against the United States in 1996 and 1998. The network executed the 1992 hotel bombing in Yemen and the August 1998 truck bombings of US embassies in Nairobi and Dar es Salaam, which killed 224 people.

Following the 2001 invasion, bin Laden avoided capture until American forces killed him in Pakistan in 2011. While the organization later encountered operational competition from the Islamic State, it continues to operate regional affiliate networks across parts of Africa.
