Today, the Council on Foreign Relations (CFR) released a Ploughshares-funded Task Force report, "U.S. Nuclear Weapons Policy", endorsing some of the most important steps necessary to realize the vision of a world free of nuclear weapons.    Its recommendations include support for the Comprehensive Nuclear Test Ban Treaty; limiting the purpose of U.S. nuclear weapons to deterrence; working quickly with Russia to conclude a follow-on agreement to the START Treaty that expires this year; and working to halt the production of weapons-usable fissile materials worldwide.  These are all key goals that Ploughshares supports.
