9/11 Attacks: Twenty-Five Years Later

Twenty-five years after the September 11 attacks, the nation’s national security architecture is more complex than ever. This symposium will feature a keynote panel of former secretaries of homeland security, which will serve as the Kenneth A. Moskow Memorial Lecture. The two following panels will include senior leaders across various sectors, reflecting on the evolving counterterrorism landscape and U.S. resilience efforts, interagency coordination, domestic radicalization and terrorist finance strategies, as well as technological and soft power tools shaping the threat landscape today.

This symposium is part of the series, Twenty-Five Years Later: Reflections on 9/11 and the War on Terror, which examines how the legacy of the 9/11 attacks and the war on terrorism continues to shape U.S. foreign policy, domestic security, global affairs, defense strategy, and national security.
The keynote session will serve as the Kenneth A. Moskow Memorial Lecture, which honors the memory of longtime Council member Kenneth A. Moskow, who made this event possible through a generous bequest. His intent was to establish an annual event to bring together the leaders of the intelligence community and promote discussion on critical issues in counterterrorism.

FROMAN: Well, good afternoon, everybody, and welcome. It’s a great pleasure to welcome you to the Council’s symposium commemorating the 25th anniversary of the attacks of September 11, 2001.
Today, we’re honored to have this group of national security and foreign policy officials whose public service was defined and shaped in many ways around the events of 9/11. Between them, they’ve guided U.S. policy that has protected Americans from a repeat of that terror, and they’ve helped reform the government to meet the enormity of the challenge in front of them.
But before we get started, I wanted to just take a moment and see if we could have a moment of silence for the 2,977 people who lost their lives that day.
(A moment of silence was observed.)
Thank you.
We all remember exactly where we were on that morning. For me, my wife and I were on an airplane on our way to Mumbai, and I remember very distinctly the pilot coming on and using the exact words, “Due to a security situation in the United States, we will be returning to Frankfurt.”

CHANG: OK, I’m getting the thumbs up. Hello. Good afternoon, everybody. I know that you’ve been in session listening to accounts of the day. And today’s panel, this afternoon’s panel, is called “Eyewitness to History: The View from Washington.” So I’m going to welcome everybody on this stage in a moment. I am Juju Chang. I’m the co-anchor of ABC News Nightline. And I’m a member of the Council as well, and have been for many years. And I’ll be presiding this on-the-record conversation.
I just want to take a moment to say that I’ve spent a couple days in the last week talking to family members of those lost on 9/11. I just want to acknowledge that they continue to, you know, deal with the trauma and the pain of that day, in the ways that so many in our country did just by witnessing it. But these four on stage witnessed it in a particularly acute way, in a way that has clearly had policy implications, real-world implications, and, as Lin-Manuel Miranda said, they were in the room when it happened. So let’s just start by introducing some of you folks.
Let’s start with John Bellinger,...
