## Highlights

For decades, the United States has tried to impede nuclear proliferation networks that provide equipment to nuclear weapons development programs in countries such as Pakistan and Iran. GAO was asked to examine U.S. efforts to counter nuclear proliferation networks, specifically the (1) status of U.S. efforts to strengthen multilateral controls, (2) impact of U.S. assistance to help other countries improve their legal and regulatory controls, and (3) impact of U.S. efforts to strengthen its enforcement activities. GAO's findings focused on seven countries where network activities reportedly occurred.
