This collection of essays explores the problem of nuclear, chemical and missile proliferation. Contributors discuss the role of export controls in preventing or delaying proliferation, and contrast the relative benefits of export controls with their costs to industry and to international political relationships. Particular emphasis is placed on the challenges posed by export controls to the US-European Community partnership, and to the effects of European unity following unity in 1993. Contributors: Bill Richardson, John Harvey, Michael Elleman, Matthias Dembinski, Benoit Morel, David Fischer, Jeff Bingaman, Jan Hoekema, Harald Muller, William Burns, Richard Kauzlarich, and Reinhard Rode.
