Although may problems face international efforts to prevent the spread of nuclear weapons to additional countries in the years ahead, none is more important than gaining a lengthy extension of the non-Proliferation Treaty (NPT). Action on extension will be taken by majority vote of the over 160 parties at a conference called to consider this question in 1995. This paper will consider why a lengthy extension of the NPT is important; what options for, and obstacles to, extension exist and what the NPT's strongest supporters can offer the NPT members who are skeptical about a long extension in order to win their votes.
