The 9/11 Attacks 25 Years Later: Lessons Learned, Lessons Forgotten
Twenty-five years after the September 11 attacks, Columbia SIPA’s Institute of Global Politics will bring together leading policymakers, legal scholars, New York City leaders, and national security experts to examine the lasting legacy of one of the defining events of the 21st century. As the nation marks this solemn anniversary, this two-panel event will explore the post-9/11 transformation of American government, law, and society – from the legal architecture that emerged in the aftermath of the attacks and the reorganization of the executive branch and intelligence community, to Congress’s role and New York City’s response.
The first panel will consider the enduring impact of the decisions made after 9/11 and the lessons they offer for today’s global security challenges. The second panel will assess the environmental and health impacts on first responders, the rebuilding of Lower Manhattan, and the civic resilience required of institutions and communities to overcome tragedy.

As policymakers grapple with the future of open AI, defining “openness” has become more important than ever. This post highlights a new paper that provides a shared framework for understanding openness in foundation models and reflects several years of collaborative work led by Columbia IGP and its partners.
IGP’s Year In Review
The Institute of Global Politics (IGP) at Columbia University’s School of International and Public Affairs (SIPA) marked a third year of sustained excellence across scholarship, research, and student engagement. We hosted 135 events, reached more than 300,000 people through our livestreamed events, and generated over 10 million social media impressions while launching new IGP Initiatives and Task Forces.
Advancing open dialogue
IGP provides a forum for the open exchange of ideas and respectful discourse through its signature speaker programs. From Spotlight Interviews to the Across the Aisle series, IGP brings leaders from the public and private sectors into dialogue to share lessons learned, discuss global challenges, and find commonalities across partisan and ideological divides.
Research for impact
Based at the world’s top school for global public policy, the nonpartisan Institute of Global Politics harnesses the deep expertise and experience of leading scholars and practitioners to develop and advance evidence-based solutions to today's pressing global challenges.
Training the next generation of leaders
The IGP Student Scholars Program helps prepare Columbia students to understand and find solutions to today's global challenges. Students selected for the program benefit from the mentorship of leading practitioners and scholars, gain hands-on experience in policymaking, and engage in dialogue on the world’s toughest problems.

IGP’s signature speaker series offers a vital platform to exchange ideas, find common ground, and model civil discourse for the next generation of policy leaders.
