Monday, April 5, marks the one year anniversary of President Obama's historic unveiling of his 21
st century nonproliferation agenda. The week of the anniversary will be marked by significant steps. First, the signing in Prague of a New START Treaty that provides binding, verifiable limits on Russian nuclear weapons - reducing both sides' arsenals to levels not seen since the Eisenhower and Kennedy administrations while improving U.S. intelligence on Russia's nuclear capabilities. Second, the Administration will unveil a Nuclear Posture Review that communicates both how this Administration views the limited but important role of nuclear weapons in ensuring our security, and how it intends to keep our arsenal safe and effective. Third, in ten days Washington will welcome forty world leaders for a ground-breaking summit on the safety of nuclear materials - in an age of terrorism, the most important security threat we face. This ambitious agenda seeks to make up for eight years of neglect from President Obama's predecessor.
