Over at the White House blog, Laura Holgate, Senior Director for WMD Terrorism and Threat Reduction, writes about prepreations for the 2012 Nuclear Security Summit to be held in Seoul, South Korea.
"Even though I’d been aware of many of these events as they happened, it was really impressive to see the progress piled up: over 400 kg of highly enriched uranium removed from over 10 countries – enough for 16 nuclear bombs. A dozen new countries joining the key international treaties. Over a dozen new nuclear security training and research “centers of excellence” opening their doors. Key tools for international cooperation on nuclear security, such as UN Security Council Resolution 1540 and the G8 Global Partnership Against the Spread of Weapons and Materials of Mass Destruction extended into the next decade. Increased resources for the International Atomic Energy Agency’s support to its member states to improve security on nuclear materials. Tens of tons of Highly Enriched Uranium permanently destroyed by Russia and the US – raw material for thousands of nuclear weapons. Nuclear industry players adopting “Principles of Conduct” including commitments to secure materials at their facilities, and working together through the World Institute of Nuclear Security to identify and promote best practices in nuclear security. INTERPOL setting up a new radiological-nuclear center to bring law enforcement tools to bear more effectively on nuclear smuggling. "
