The French disarmament policy and diplomacy, under the Fifth Republic, is marked by continuity, rationality and flexibility. Their coherence rests on an original conceptual framework and principles, despite the different personal equation imposed by each of the five presidents who have led France since 1958. In addition, the French discourse has adapted relatively easily to the changes in the international strategic order after the fall of the Berlin Wall. However, the constraints imposed by the construction of the European Union – the Treaty of Maastricht (1992) and the Treaty of Amsterdam (1997) with the CSSP – progressively involve a europeanization of France’s diplomacy of disarmament. – Summary AFRI-2001
