Nuclear Weapons: The Road to Zero is a 1998 book edited by Joseph Rotblat. The book is based on the Pugwash Conferences on Science and World Affairs, and in particular on a detailed international study published in 1993 on the importance of, and practical mechanisms to, eliminate nuclear weapons. This monograph is a series of essays that describe the many complex technical, economic, legal and political issues involved. Contrary to the approach of nuclear powers -- that these weapons are needed for national security -- is the "no longer fanciful dream" of a nuclear-weapon-free world. Rotblat suggests that this is "a sound and practical objective, which could be realized in the foreseeable future."
