"In important ways, the world is at a nuclear crossroads. The complex and dynamic nuclear landscape presents us with challenges along at least four axes: regional nuclear proliferation, nuclear terrorism, great power nuclear relations, and the security implications of increased interest in nuclear energy. These problems are interrelated in ways that the national security community does not fully understand. Strategy and policy frameworks do not address them in sufficiently integrated fashion. New conceptual thinking is required to develop a more unified understanding of and approach to managing the risks and opportunities posed by these 21st-century nuclear challenges."
