Two analysts from the Belfer Center for Science and International Affairs at Harvard Kennedy School, Matthew Bunn, co-principal investigator of the Project on Managing the Atom, and Gary Samore, the center’s executive director for research, spoke with the Harvard Gazette about North Korea’s nuclear program and what the latest test means for relations between the government of leader Kim Jong-un and other nations, and how the blast may affect global efforts to limit nuclear weapons.

North Korea’s report that it tested a hydrogen bomb this week set off alarm bells around the world. Though analysts are casting doubt on the nature of the detonation, Pyongyang’s fourth nuclear test is a reminder of the regime's unpredictability. How serious is this action and how should foreign powers respond? Belfer Center experts Graham Allison, Jieun Baek, Matthew Bunn, Nicholas Burns, Olli Heinonen, John Park, Gary Samore, and William Tobey weigh in on the significance and implications of North Korea’s latest nuclear test.
