摘要：A debate over the future of the US nuclear arsenal is at a pivotal moment. The Obama administration has proposed to Congress a budget that calls for modernization of the US “nuclear triad” of missiles, submarines, and bombers. This proposal is notable because presidential administrations and Congress have largely neglected US nuclear forces for over two decades; consequently, each part of the triad has aged or is aging rapidly, and according to National Security and Nuclear Weapons in the 21st Century (2008), “The United States does not have the ability to produce new nuclear weapons.”1.
