Former President George W. Bush spoke at the Sept. 11 memorial at Shanksville, Pennslyvania, where United Flight 93 crashed after passengers fought with and overcame the hijackers.
Bush reflected on the bravery of those passengers amid the carnage taking place throughout the country.
“Here, the intended targets became the instruments of rescue, and many who are now alive owe a vast, unconscious debt to the defiance displayed in the skies above this field,” he said.
Bush spoke about the unity and heroism that took place in the days after the attacks, the sights of people grabbing another person’s hand and “rally to the cause of one another.”
He also warned about the still lingering threat of terrorism, both foreign and domestic.
Bush said there is “little cultural overlap between violent extremists abroad and violent extremists at home.”
“They are children of the same foul spirit and it’s our continuing duty to confront them,” he said.
Bush also commended the country’s veterans and armed service members who have served since the attacks.
“Nothing that has followed, nothing, can tarnish your honor or diminish your accomplishments. To you and the honored dead, our country is forever grateful,” he said.
