On 8 April, 2010, President Obama and Russian President Medvedev signed the New Strategic Arms Reduction Treaty, or "New START," lowering the limit on deployed strategic nuclear weapons by either nation. The following week, President Obama hosted the Nuclear Security Summit in Washington, D.C., the stated purpose of which was to address "the threat of nuclear materials in the hands of terrorists or criminals." Against this backdrop, three panels of distinguished experts on nuclear policy convened in Washington, D.C. to offer critical assessment of President Obama's nuclear agenda-and weather it is compatible with maintaining an American nuclear arsenal that can credibly, reliably, and effectively address today's threats.
