In April 2010, forty-seven nations attended the first-ever Nuclear Security Summit in Washington and made commitments to strengthen the global nuclear security regime and reduce the risk of nuclear terrorism. This report tracks those commitments and provides a “status update” on how countries are faring with their commitments one year later. It aims both to highlight the significant progress that has been made in the past year and to provide a basis for looking forward to the 2012 summit in South Korea.
