25 Years After September 11: The Lasting Impact of the Attacks
The September 11, 2001 attacks changed various aspects of global society, including security and surveillance, 25 years later.

On September 11, 2001, at 8:46 AM, a plane struck the North Tower of the World Trade Center in New York City. This event occurred 43 minutes before the New York Stock Exchange was set to open, which was immediately canceled after the impact. The second plane from American Airlines collided with the South Tower, leading to a complete halt of financial activities in the region and resulting in a series of global repercussions.
According to various reports, the attacks resulted in significant transformations, not only in the United States but also worldwide. Airport security measures were strengthened, counter-terrorism gained new guidelines, and surveillance increased in several countries, including Portugal. These changes are still evident 25 years after the attacks.
Studies and debates about the impact of the September 11 attacks have emerged over the years, raising questions about how the world has truly changed. The Observador, in recent articles, emphasizes that despite some transformations, many aspects of daily life have remained similar, questioning whether the perceived changes are as substantial as the reality.

The emotional impact of the events of 2001 is unforgettable, with many people still recalling where they were at the moment of the attacks. This personal connection to the date has sparked discussions about collective memory and the social consequences that followed.
In addition to changes in security and surveillance, the attacks led to an increase in security alerts and restrictions. The governmental response to the attacks, including immigration policies and counter-extremism measures, has altered how countries interact with each other and address security issues.
In reflections on September 11, various entities and individuals have explored its significance and the lessons learned over the years, with discussions revisiting both the events themselves and their lasting repercussions on today's society.
