Iran’s pursuit of nuclear weapons capability is the most urgent national security threat facing the United States. For the last four years I have served as the co-chair of the Bipartisan Policy Center Task Force on Iran, working to help articulate and advocate a realistic and robust approach to this pressing problem. Our latest report –published February 1, 2012–lays out a comprehensive strategy that we continue to believe offers the best hope for a peaceful resolution of Iran’s nuclear challenge, without sacrificing vital national interests or security.
