Abstract
Following Milward and Moravcsik’s injunction that the analysis of European integration requires evidence-based empirical observation, this article focuses on one area of state activity - the armed forces - to illustrate the current trajectory of state transformation in Europe. The article argues that European armed forces are becoming ‘transnational’. They are undergoing a process of concentration and transnationalization. Budgets and resources are focusing on specialist military units, organized into joint rapid reaction forces, which are co-operating at an increasingly lower level with other similarly concentrated units in other states. The article concludes by suggesting that the transnationalization of the armed forces reflects the wider transformation of states; across a range of activities, states are contracting to concentrate on their core functions and co-operating ever more closely with each other to fulfil them.
