The Black Sea region is one of the world's critical crossroads, a strategic intersection of east -- west and north -- south corridors that enable the free flow of people, ideas, and goods from Asia to Europe and from former Soviet territory to the Middle East and Africa. It is also the center of the world's nuclear black market.

Highlighting the danger posed by nuclear terrorism and the need for an effective response, President Barack Obama came to office promising to "secure all vulnerable nuclear materials around the world within four years." The necessity of this goal is unquestioned.

The Nuclear Posture Review was mandated by Congress to establish US nuclear policy, strategy, capabilities and forces for the next five to 10 years. In theory, it was intended to further President Obama's Prague agenda of reducing nuclear dangers and to work toward a world without nuclear weapons, but with global security.

As South Korea prepares for the second Nuclear Security Summit, scheduled to take place in Seoul next March, the momentum for collective international action on nuclear terrorism must be sustained. In the months before the 2012 talks, states will have to work together to retain focus on the summit's ultimate goal -- securing vulnerable nuclear material worldwide -- or else risk taking a step backward in the fight against the menace of nuclear terrorism.
