Back to the Élysée
On May 16, 2007, Levitte was appointed as diplomatic advisor and sherpa to President Nicolas Sarkozy, and the head of a future American-style National Security Council. The nature and extent of his new role were not immediately clear. While some commentators suggested he would not eclipse Minister of Foreign and European Affairs Bernard Kouchner, Levitte was elsewhere referred to as "seemingly the true Minister of Foreign Affairs." Despite assertions made while campaigning, it was still unclear to what extent President Sarkozy would treat national security and foreign affairs as the "reserved domain" of the presidency. Levitte left office on May 15, 2012 following Sarkozy's defeat in the 2012 presidential election, and joined Rock Creek Global Advisors in Washington, DC..
