In the first military action in the 45-year history of the North Atlantic Treaty Organization (NATO), U.S. fighter planes shoot down four Serbian warplanes engaged in a bombing mission in violation of Bosnia’s no-fly zone.
The United States, 10 European countries, and Canada founded NATO in 1949 as a safeguard against Soviet aggression. With the end of the Cold War, NATO members approved the use of its military forces for peacekeeping missions in countries outside the alliance and in 1994 agreed to enforce U.N. resolutions enacted to bring about an end to the bloody conflict in the former Yugoslavia. In 1994 and 1995, NATO planes enforced the no-fly zone over Bosnia-Herzegovina and struck at Bosnian Serb military positions and airfields on a number of occasions.
On December 20, 1995, NATO began the mass deployment of 60,000 troops to enforce the Dayton peace accords, signed in Paris by the leaders of the former Yugoslavia on December 14. The NATO troops took over from a U.N. peacekeeping force that had failed to end the fighting since its deployment in early 1992, although the U.N. troops had proved crucial in the distribution of humanitarian aid to the impoverished population of Bosnia. The NATO force, with its U.S. support and focused aim of enforcing the Dayton agreement, proved more successful in maintaining the peace in the war-torn region.
