The United States and Russia signed a new strategic arms reduction treaty - known as New START - on April 8, 2010. This treaty is designed to replace the 1991 Strategic Arms Reductions Treaty (START), which expired, after 15 years of implementation, on December 5, 2009. This report provides an overview of New START, including a comparison to the original START Treaty, the belief of the Obama Administration and outside analysts that New START will enhance U.S. national security, and the criticisms of those who say that New START (and, indeed, the entire issue of U.S.-Russian arms control) is a distraction from more important items on the nonproliferation agenda.
