Are states with nuclear weapons immune from externally driven efforts to promote regime change? Libya’s Qaddafi came clean, was driven from power, and ultimately killed by rebels.

Are regime change policies justified by nuclear proliferation by outlier states?

Ellen Laipson, Antonio Guerriero, Bijan Khajehpour, Danielle Pletka, and Bruno Tertrais discuss these cases and more. Share your comments and questions below.
