In 1957 the Europeans created the European Economic Community, which is the basis for today’s European Union. Despite its name, this Community has not been able to promote communitarianism in the sense used in this book, namely a policy seeking to bolster the group. Creating a European organisation based on community capitalism has involved grappling with complex questions: who is a partner and who is a foe? Should Europeans companies be favoured or not? Should Europeans be capable of defending themselves independently, or through the US alliance? This chapter will show first that during the Cold War (1947–1991) defence and diplomacy were largely coordinated on a North Atlantic scale through NATO, despite numerous attempts to create a ‘European power’ (including with a nuclear arsenal). Second, some form of European protectionism nevertheless thrived in specific areas, such as agriculture and aeronautics, but surprisingly not in energy. Third, the ubiquity of national industrial policies led European institutions to counterbalance these policies through free-market rules rather than the creation of Europe-wide industrial policy.
