As the United States takes the lead on international efforts toward a world free of nuclear weapons, Charles Ferguson, Director of the Council on Foreign Relations-sponsored Independent Task Force, and Task Force member Scott Sagan discussed key recommendations on ways to reduce the world's nuclear arsenal. The Task Force, co-chaired by former Secretary of Defense William Perry and former National Security Adviser Brent Scowcroft, states that while "the geopolitical conditions that would permit the global elimination of nuclear weapons do not currently exist," steps can be taken now to diminish the danger of nuclear proliferation and nuclear use.  The report also evaluates the best way to contain the threat of proliferation posed by Iran, North Korea and other potential nuclear threats.
