Arms Proliferation and Control

Featured

The U.S.-Soviet nuclear arms race ended in détente, but nuclear development efforts and WMD proliferation in India, Pakistan, North Korea, and Iran have caused geopolitical instability since the Cold War's end. RAND has applied strategic analysis to nuclear confrontation scenarios and international deterrence efforts since its earliest work on game theory, with particular focus on the roles of both diplomacy and missile defense systems in global as well as regional security.

    Nuclear Testing Not Needed Now

    Trump administration officials are reported to have recently discussed conducting a nuclear test, breaking a moratorium the United States has observed since 1992. Such a move is not necessary to ensure the reliability of the U.S. arsenal and could increase threats to U.S. and allied security by giving a green light to others to conduct nuclear tests.

    Reimagining Conventional Arms Control

    For much of the past 30 years, conventional arms control (CAC) has played a historic role in ensuring the security of Europe. But today, the CAC regime is outdated and mostly irrelevant. New approaches to CAC are needed to address the challenges posed by the current security environment.

    New START Is Not NAFTA

    The 2010 New START Treaty with Russia reduces long-range nuclear arms. President Trump may seek a different deal, however, as he did in renegotiating NAFTA. But NAFTA talks succeeded because America had predominant leverage and because Canada and Mexico are friends. Neither holds true with Russia.

    The Military Case for Extending New START

    The most prudent course of action would be for Washington to extend the U.S.-Russia New START agreement before it expires in February 2021. This would constrain Russia's nuclear forces covered by the treaty for five more years. And it would buy time to pursue multilateral negotiations that also include China.

    One Year After Singapore: The North Korea Problem Is Bigger Than Nukes

    After two summits between the United States and North Korea, and little to show in the way of deliverables on dismantlement, hopes that a third summit may yield a denuclearization deal seem a bit unrealistic. Essentially, there has been no indication of intent on Kim's part to denuclearize. But the North Korea problem is much greater than nukes.

    Downplaying North Korea's Missile Tests Carries Risks

    North Korea test-fired short-range ballistic missiles for the first time in 18 months. President Trump is downplaying the tests, refusing to call them a violation of U.N. Security Council resolutions. But if North Korea starts testing longer-range missiles, it could become harder for Washington to return to talks, risking the end of diplomacy with Pyongyang altogether.
