The European Union and the United States are on the verge of agreeing to a transatlantic free trade agreement. The proposed Transatlantic Trade and Investment Partnership is aimed at boosting EU and US economic growth, but the negotiating partners have not excluded the defence sector from negotiations. Europe is at a tipping point regarding the rationale for its defence-industrial integration efforts. Any TTIP extending to the defence sector will raise questions about the nature of the European Defence Technological and Industrial Base, and, crucially, how it impacts the North Atlantic Treaty Organisation and the Common Security and Defence Policy.
