The treaty was initiated by the Pleven plan, proposed in 1950 by then French Prime Minister René Pleven in response to the American call for the rearmament of West Germany. The formation of a pan-European defence architecture, as an alternative to West Germany's proposed accession to NATO, was meant to harness the German military potential in case of conflict with the Soviet bloc. Just as the Schuman Plan was designed to end the risk of Germany having the economic power on its own to make war again, the Pleven Plan and EDC were meant to prevent the military possibility of Germany's making war again.
