March 7, 1966. In a rare handwritten letter to President Johnson, General de Gaulle states the reasons for his decision to withdraw France from the military aspects of NATO.
“…France considers that the changes that have occurred, or are in the process of occurring, since 1949, in Europe, Asia, and elsewhere, as well as the evolution of her own situation and her own forces, no longer justify, in so far as she is concerned, the arrangements of a military nature made after the conclusion of the Alliance, either jointly in the form of multilateral agreements, or by special agreements between the French Government and the American Government.”
This decision led to the withdrawal of American bases from France and the relocation of NATO headquarters from Paris to Brussels. To read the full translation, see the Foreign Relations of the United States Series.
