Americans are commemorating the 25th anniversary of the September 11, 2001 attacks with ceremonies in New York, at the Pentagon and near Shanksville, Pennsylvania. Relatives at ground zero will again read the names of nearly 3,000 people killed in the attacks and observe moments of silence tied to the day’s chronology.
For the first time, the New York observance is adding a separate silence for people who later died after illnesses associated with toxic dust from the World Trade Center collapse. President Donald Trump is scheduled to attend the Pentagon ceremony, while Vice President JD Vance is expected at the National September 11 Memorial in New York.
An AP-Ipsos poll found that about half of U.S. adults named September 11 among the most important historic events in their lifetime, though the share differs sharply by age. Only about one in ten adults said they planned a specific commemorative activity, while many survivors, relatives and witnesses described private remembrance.
The attacks led to wars in Afghanistan and Iraq, new federal security institutions, expanded surveillance authorities and lasting changes to air travel and finance. Accused plot organizer Khalid Sheikh Mohammed remains untried more than two decades after capture, reflecting legal disputes tied to torture, evidence and military commissions. Muslim Americans also experienced increased suspicion and hate crimes after the attacks while becoming more visible in public life during the subsequent twenty-five years.
At the edition deadline, the total number of later deaths caused by exposure-related disease remains difficult to determine, and polling describes public memory rather than a single national interpretation. The next documented developments will be the day’s memorial ceremonies and official health-program announcements and the separate military-commission schedule now projecting a 2028 trial.
