state, no matter how powerful, can solve urgent problems, fight for development and bring an end to all crises ... France wants the UN to be the centre of global governance". In his 1953 address to the United States Committee for United Nations Day, U.S. President Dwight D. Eisenhower expressed the view that, for all its flaws, "the United Nations represents man's best organized hope to substitute the conference table for the battlefield". UN peacekeeping missions are assessed to be generally successful. An analysis of 47 peace operations by Virginia Page Fortna of Columbia University found that UN-led conflict resolution usually resulted in long-term peace. Political scientists Hanne Fjelde, Lisa Hultman and Desiree Nilsson of Uppsala University studied twenty years of data on peacekeeping missions, including in Lebanon, the Democratic Republic of the Congo, and the Central African Republic, concluding that they were more effective at reducing civilian casualties than counterterrorism operations by nation states. Georgetown University professor Lise Howard postulates that UN peacekeeping operations are more effective due to their emphasis on "verbal persuasion, financial inducements and coercion short of offensive military force, including surveillance and arrest", which are likelier to change the behavior of warring parties. Awards A number of agencies and individuals associated with the UN have won the Nobel Peace Prize in recognition of their work. Two secretaries-general, Dag Hammarskjöld and Kofi Annan, were each awarded the prize (in 1961 and 2001, respectively), as were Ralph Bunche (1950), a UN negotiator, René Cassin (1968), a contributor to the Universal Declaration of Human Rights, and the US Secretary of State Cordell Hull (1945), the latter for his role in the organization's founding. Lester B. Pearson, the Canadian Secretary of State for External Affairs, was awarded the prize in 1957 for his role in organizing the UN's first peacekeeping force to resolve the Suez Crisis. UNICEF won the prize in 1965, the International Labour Organization in 1969, the UN Peacekeeping Forces in 1988, the International Atomic Energy Agency (which reports to the UN) in 2005, and the UN-supported Organisation for the Prohibition of Chemical Weapons in 2013. The UN High Commissioner for Refugees was awarded in 1954 and 1981, becoming one of only two recipients to win the prize twice. The UN as a whole was awarded the prize in 2001, sharing it with Annan. In 2007, IPCC received the prize "for their efforts to build up and
