The New Strategic Arms Reduction Treaty (New START) promises to lock in significant reductions in U.S. and Russian strategic arsenals by establishing lower ceilings on deployed weapons. The treaty’s verification provisions are means to that end--providing confidence that the sides are complying with those lower limits. Although the goal is to establish the high confidence levels maintained during the 15 years of the original START (1994-2009), the successor agreement will achieve that goal with more focused and up-to-date methods, including innovative verification provisions for deployed warhead ceilings. START’s multilayered limits and the elaborate verification measures flowing out of them were born of the Cold War. New START verification can be streamlined in accordance with the new, simplified limits and in response to post-Cold War realities. In assessing the new treaty, it is critical that verification provisions be judged by how well they fulfill their core function.
