Focusing on conventional weapons, rather than nuclear, biological and chemical ones, this book draws attention to important differences, within the EU, between the trade in finished weapons and the technology used to make them. It examines West European efforts since 1945 to manage both sides of conventional defence-related trade, and the political, industrial, technological and conceptual obstacles to effective mulitlateral co-ordination and regulation. The book argues that, in current European and international circumstances, recent EU initiatives have limited prospects and may prove to be counterproductive.
