The Nuclear Threat Initiative's second public assessment of nuclear materials security conditions around the world shows an improving situation with seven countries removing all their stocks of weapons-usable nuclear material but finds a need for an accountable global system for preventing nuclear terrorism. The MacArthur-supported Nuclear Materials Security Index was created to assess the security of nuclear materials around the world and to engage governments to take actions and provide assurances about the security of the world's deadliest materials. It has sparked international discussions about priorities required to strengthen security. This latest edition comes just months ahead of the third Nuclear Security Summit in the Netherlands, which will gather more than 50 world leaders to discuss the issue.
