In March 2011, after having been criticized for his unwillingness to support the Egyptian and Tunisian revolutions, and persuaded by the philosopher Bernard-Henri Levy to have France actively engage against the forces of the Libyan leader, Muammar Gaddafi, Nicolas Sarkozy was amongst the first Heads of State to demand the resignation of Gaddafi and his government, which was then fighting a civil war in Libya. On 10 March 2011, Nicolas Sarkozy welcomed to the Elysee Palace, three emissaries from the Libyan National Transitional Council (NTC), brought to him by Bernard-Henri Levy who mediated at the meeting. Nicolas Sarkozy promised them a no-fly zone would be imposed on Gaddafi's aeroplanes. He also promised them French military assistance. On 17 March 2011, at the behest of France, resolution 1973 was adopted by the Security Council of the United Nations, permitting the creation of a "no fly" zone over Libya, and for the undertaking of "necessary measures" for the protection of the country's civilian population. On 19 March 2011, Nicolas Sarkozy officially announced the beginning of a military intervention in Libya, with France's participation. These actions of Nicolas Sarkozy were favorably received by the majority of the French political class and public opinion.
