With the imminent fall of the Libyan regime and enormous changes taking place across the Arab world, the national security landscape has dramatically altered.

But the protestors in Tahrir Square or in Tunis did not wave banners hailing Osama bin Laden or Ayman al-Zawahiri—instead, they rejected their autocratic governments. Will these newfound voices also help in rejecting Muslim extremism and other violent ideologies? What will the next ten years bring? Will terrorism still be the overarching threat it has been since 9/11? It is clear that America must rethink its strategies for countering the threat of terrorism going forward.

To discuss these issues, The Wilson Center brings together top experts from Congress, the intelligence community, the media, and academia in an event moderated by the Washington Post's David Ignatius to examine how the threat is changing and how homeland security, military, and intelligence strategies should evolve to deal with it.

The National Conversation at The Wilson Center, a recent initiative, provides a safe political space for deep dialogue and informed discussion of the most significant problems and challenges facing the nation and the world. Nonpartisan and civil, The National Conversation provides the level of discourse the nation deserves through thoughtful and challenging explorations of vital issues.

Over the past ten years, The Wilson Center has convened a careful, reasoned dialogue about the many critical issues and questions raised by the attacks on September 11, and its experts have contributed to the discourse in articles, live interviews, and panel discussions. Here is a selection of The Wilson Center's decade of scholarship surrounding 9/11.
