The maintenance of international peace and security represents the primary purpose behind the establishment of the United Nations. It reflects the intentions and desires of its founders who sought to establish an international organization for achieving this end. It is a prerequisite to any other purpose of the United Nations. Without it no friendly relations, no international cooperation, and no harmonization of nation’s actions could be achieved. Because of the importance of international peace and security, the founders of the United Nations insisted on it and emphasized it in the preamble and the Charter of the Organization. They stated all the possible principles, methods and procedures which are to be followed to attain this end. The theme “we are going to create a collective security system, and this time we are going to make it work,” dominated the entire process of planning and formulating the United Nations Charter. The Charter provided a system for the pacific settlement or adjustment of disputes, and the use of collective measures in threat to or breaches of peace and acts of aggression. The first method provided by the system is that of seeking peaceful settlement or adjustment of disputes and situation by peaceful means listed in the Charter. The second method is that of taking collective actions (measures) of a coercive nature for the prevention and removal of threats to the peace and for the suppression of acts of aggression and other breaches of the peace. Through these two methods delineated in Chapter VI entitled “Pacific Settlement of Disputes” and Chapter VII entitled “Actions with Respect to Threats to the Peace, Breaches of the Peace, and Acts of Aggression” of the Charter, the United Nations primarily exercises its role in maintaining international peace and security.
