The governments of the United States, United Kingdom, and French Republic each understand the threat of nuclear terrorism and share the collective responsibility to inform and strengthen international measures designed to secure sensitive information, technology or nuclear material from access by terrorists, and to develop emergency response measures. In recognition of these shared principles, consistent with our rights and obligations under the Non-Proliferation Treaty, our three governments are taking the following initial steps:
INFCIRC/225/Rev. 5 recognizes that nuclear security protection levels are critically dependent upon the attractiveness of nuclear materials to potential terrorist adversaries with intent to assemble a nuclear explosive device. We will actively engage in international workshops to address graded approaches for the characterization of nuclear material attractiveness to further enhance the effectiveness and sustainability of physical protection measures.
We have the specialized knowledge and capability to diagnose, render safe, characterize and dispose of a nuclear threat device. We have a focused effort to continually enhance the technical capabilities of our emergency detection and response assets to any such threat. As such we will seek, wherever possible, to engage with the international community to further strengthen worldwide preparedness to contend with the threat of nuclear terrorism.
