Twenty-five years after September 11, 2001, the legal, political, and social transformations set in motion in its aftermath continue to shape governance, conflict, and everyday life. This opening plenary brings together three distinguished leaders whose scholarship, advocacy, and organizing have been central to understanding and challenging the enduring legacies of the post 9/11 era. Drawing on perspectives from international law, constitutional law, civil rights advocacy, and community organizing, the panel will examine how responses to 9/11 reconfigured the relationship between security and liberty. The conversation will explore the evolution of the legal frameworks that have governed armed conflict, detention, surveillance, targeted killing, and other areas that have seen dramatic expansions of executive power, alongside the expansion of domestic security institutions and the profound consequences of racialized national security policies for Muslim, Arab, and South Asian communities in the United States. The discussion will also consider how these developments have reshaped democratic institutions, normalized exceptional forms of state power, and influenced broader debates about immigration, policing, and civil rights. Looking ahead, the panelists will reflect on the future of the legal and political architectures built in the name of national security, asking what has been entrenched, what may be changing, and what alternative visions of freedom, justice, and collective security are possible. As the opening conversation for the symposium, this plenary will set the stage for a critical reassessment of the post-9/11 era and invite participants to imagine futures beyond the frameworks of fear, exclusion, and militarization that have defined the past quarter century.
