Military expenditure as a proxy for state power The case of France Etymologically, "power" is the capacity to do and to reach one's goals. The main power of a state is to offer a good level of security to its citizens, i.e. the ability to satisfy their main needs, free of any threat. Political power introduces the idea of a control, ascendency or command of a public entity on others. As everybody knows since Adam Smith, "The first duty of the sovereign, that of protecting the society from the violence and invasion of other independent societies, can be performed only by means of a military force" (A. Smith, 2007, p.536). Said otherwise, a power is able to assure the integrity of the interests of the nationindependency; territory; style of government; life of people...-against any threat. This was true at the time of Smith and it remains true today. Since 1990, the systemic antagonism long evoked to explain the Cold War is no longer on the agenda with the collapse of the Soviet Union and Warsaw Pact. For the proponents of the theory of globalization such as Ohmae, Krugman, Fukuyama or Sachs (Fontanel, 2004), growing economic interdependence tends to reduce government intervention in the economy because the generalization of market rules is a factor of solidarity and peace. The idea of an inevitable pacification of international relations allowed by international trade takes us back to the origins of liberal theory, where increasing economic interdependence based on market principles increases the economic prosperity of each nation participating in beneficial exchange, while leading to the reduction of the economic role of the state. In this logic, policy should gradually give way to economic imperatives, on the basis of scientific results not polluted by short-term political concerns. But the "end of history", mentioned by Francis Fukuyama (1999) in the post Cold war, has not been subsequently validated 1. Democracy and economic liberalism, then presented as key requirements to establish a permanent and global peace, still does not seem to be on the world agenda. Indeed, this analysis forgets the "political" objectives pursued by states through their policies, including the desire to increase their power on the international scene. In contrast, in a "neo-mercantilist" perspective, the international economy is increasingly the result of complex national strategies, each state seeking to promote its own interests on the world stage. In this regard, world economical and technological competition is fierce, not only among private companies, but also among states and regions 2. Wars still exist. The territories of Afghanistan and Iraq are still at risk, like Ukraine,
