Course Description

Applying New Tools and Technologies to Today's Security challenges on the Korean Peninsula
In 2017, North Korea tested a missile capable of delivering a powerful thermonuclear weapon against cities throughout the United States. How do scholars study international security challenges like the spread of nuclear weapons? In this course, students will develop an open source intelligence toolkit applicable to a broad universe of international security challenges, with special focus on nuclear weapons and North Korea. No prior knowledge is assumed, and students outside political science are encouraged to participate. The tools covered, such as satellite imagery, have broad applicability beyond nonproliferation, to areas such as human trafficking, climate change, oceans policy, and counterterrorism.
