The 2011 Libya campaign highlighted the divergence of interests between France and Germany within the European Union and the North Atlantic Treaty Organization (NATO) in matters of Middle East and global security. This divergence calls for a reassessment of the meaning of their bilateral cooperation, as defined in the Treaty of Friendship between France and Germany, otherwise known as the Élysée Treaty, signed on 22 January 1963 by Chancellor Konrad Adenauer and President Charles de Gaulle. This article focuses on France, which engaged militarily in Libya cooperating with the United Kingdom as its principal European partner. Germany, for reasons explained by its history, political culture, and the nature of its federal system, chose to abstain in the United Nations vote to authorize the campaign. These differences between France and Germany suggest a contrast in their respective security and, particularly defense, policy objectives on the fiftieth anniversary of the Élysée Treaty.
