Professor Lauren Sukin will speak at the MIT Security Studies Program's Wednesday Seminar.How will the intensifying political dysfunction in the United States affect Washington's credibility in the nuclear domain? A rich body of literature examines the degree to which domestic political divisions inhibit effective policymaking. However, this literature has largely siloed foreign policy, viewing it as insulated from many of the troubles of domestic politics. Yet in the nuclear security domain, where the United States must maintain challenging extended deterrence commitments, domestic politics increasingly has destabilizing potential. Drawing on a novel survey experiment fielded in six U.S. allies and partners, the research presented in this seminar tests how four defining characteristics of U.S. policymaking — political party, partisanship, polarization, and divided government — affect foreign publics' perceptions of U.S. nuclear credibility. This study has important implications for our understanding of how the domestic political environment shapes America's international leadership in nuclear politics.

MIT Media Lab’s City Science group explores how innovation can drive the creation of more adaptive, responsive, and sustainable urban ecosystems. This will require not only harnessing cutting-edge technologies—such as AI-driven urban modeling, agent-based simulations, and decentralized energy systems—but also rethinking traditional paradigms of mobility, governance, and public space to ensure inclusivity and resilience. Research scientist Luis Alonso will discuss challenges and opportunities for innovation in urban development, drawing from ongoing research and projects that aim to redefine the way we live, work, and interact in the cities of tomorrow.Register for this MIT Horizon webinar.
