A new generation of advanced conventional arms developed during the late 1960s and 1970s, ranging from antitank guided missiles to scatterable land mines, promises to buttress the defensive capabilities of their possessors. Selective transfer of such new weapons in certain cases may be a useful nonproliferation tactic. However, the fungibility of selective arms transfers with other security related nonproliferation measures, and particularly with security guarantees, appears limited. Moreover, not only would that tactic have little impact on other compelling proliferation incentives, but it would incur important risks. Nonetheless, those risks may be less than the risks and costs of nuclear proliferation in conflict-prone regions. And they may be minimized by suitable policies. The dilemma of having to choose between so using arms transfers for nonproliferation purposes and continued pursuit of global conventional arms sales restraint has been overdrawn. In contrast with recent efforts to restrain the spread of nuclear weapons, efforts to foster multilateral conventional arms restraint have proved unavailing. Various factors explain that pattern of success and failure, not least of all the different international norms in the respective areas.
