INTERNATIONAL PEACE AND SECURITY
The first purpose of the UN, as stated in Article 1 of its charter, is the maintenance of international peace and security. To this end, the organization is required "to take effective collective measures for the prevention and removal of threats to the peace, and for the suppression of acts of aggression or other breaches of the peace, and to bring about by peaceful means … adjustment or settlement of international disputes or situations which might lead to a breach of the peace." The UN has undertaken this heavy responsibility with varying levels of success over the years. However, in the nuclear era, international security in the absence of an organization like the United Nations is unimaginable. More than 1,780 UN peacekeepers died in the service of international peace and security between 1945 and 2002. In recognition of their invaluable contribution to world peace, the United Nations peacekeeping forces were awarded the Nobel Peace Prize in 1988.
