Washington, Sep 11 (V7N)- September 11, 2001, remains one of the darkest days in modern US history, when coordinated terrorist attacks claimed 2,977 lives and fundamentally changed the course of American and global affairs.

On that day, 19 Al-Qaeda hijackers carried out coordinated attacks using four passenger aircraft. Two planes crashed into the World Trade Center’s Twin Towers in New York, while a third struck the Pentagon, the headquarters of the US Department of Defense. The fourth aircraft crashed in a field in Pennsylvania after passengers attempted to intervene.

The attacks shocked the world and triggered sweeping changes in US domestic security, foreign policy and military strategy. Twenty-five years later, their consequences continue to shape international politics, intelligence operations and the geopolitical landscape of the Middle East.

Just days after the attacks, then-US President George W. Bush announced a global “War on Terror.” Later in 2001, US-led forces launched military operations in Afghanistan against the Taliban and Al-Qaeda. The campaign was followed by the controversial US-led invasion of Iraq in 2003.

The wars in Afghanistan and Iraq continued for years and were accompanied by drone strikes, expanded surveillance programs and the detention of terrorism suspects at facilities including Guantanamo Bay. These measures generated intense international debate over national security, civil liberties and human rights.

The attacks also exposed serious weaknesses in the US intelligence system. Investigations found that the CIA and FBI had access to separate pieces of information that, if properly shared and assessed, might have helped prevent the attacks. Poor coordination and failures in analyzing the available intelligence were identified as major shortcomings.

In response, the United States significantly reorganized its intelligence and counterterrorism structure. The National Counterterrorism Center was established, while the position of Director of National Intelligence was created to improve coordination among the country's intelligence agencies.

Over the past two decades, however, the US strategic focus has gradually expanded beyond counterterrorism to include growing competition with Russia and China. This shift has raised renewed concerns among analysts about whether changes in priorities could create gaps in intelligence coordination.

As the United States and the world mark the 25th anniversary of 9/11, the tragedy continues to offer a powerful lesson in national security: intelligence alone cannot guarantee safety. The ability to identify the significance of information, assess threats accurately, share intelligence effectively and act at the right moment can be just as important as collecting the information itself.

The legacy of September 11 therefore extends far beyond the destruction of that single day. It remains deeply connected to the wars, security policies and geopolitical decisions that have shaped the world for a quarter of a century.
