On October 10, 2024, H.E. Ambassador Alexander Kmentt of Austria delivered a lecture at Columbia University, calling for a paradigm shift on nuclear weapons. The well-attended event drew students, youth, and activists.
Ambassador Kmentt challenged reliance on deterrence theory, emphasizing that while it cannot be definitively proven or disproven, its risks are too great to ignore. He advocated for placing the humanitarian impacts of nuclear weapons at the heart of policy discussions, urging a shift toward disarmament and long-term global security.
The lecture was followed by a dynamic Q&A session, where attendees engaged with Ambassador Kmentt’s perspectives on disarmament challenges and solutions. A reception hosted by Dr. Ivana Hughes concluded the event, bringing together diplomats, activists, and students to continue the conversation.
