Nuclear Proliferation: What's To Worry About?

Preventing nuclear proliferation continues to be one of the biggest foreign policy challenges for the United States.  Iran is only the most recent country aspiring to develop nuclear weapons despite having signed the Treaty on the Prevention of Nuclear Proliferation.  Iran follows the example of North Korea, who formally withdrew from the treaty after acquiring the necessary technology for a bomb.  Libya was on the same path before shifting gears in the mid-2000s, while Pakistan, India, and Israel stayed out of the treaty and took their own paths to a nuclear arsenal.  Before serving as Dean of the School of Foreign Service at Georgetown University and President of the MacArthur Foundation, Ambassador Robert Gallucci spent a storied career in the State Department addressing these challenges.
