The National September 11 Memorial & Museum has marked the 25th anniversary of the 2001 attacks by highlighting the growing number of Americans too young to remember the day firsthand, warning that the country must actively pass on the "Never Forget" pledge to newer generations. The author argues this is now urgent, since more than 100 million Americans were born after or were too young at the time of the attacks, including many now serving as firefighters, police officers, service members and teachers responsible for educating today's students.

The article notes that students starting high school this autumn were born more than a decade after 9/11 and may even be taught by teachers who were not yet born when it happened. Since opening in 2014, the museum has welcomed over 28 million visitors, who view victims' names and belongings alongside twisted steel from the towers, while also learning about the solidarity shown in the attacks' aftermath. To reach those unable to visit New York, the museum runs student workshops, online programmes and teacher training sessions, aiming to equip educators nationwide to teach the history and legacy of that day.
