Ever since modern diplomacy was conceived in Italian Renaissance communes, the ideal in international relations has been a “balance of power.” However, since the founding of the United Nations 75 years ago, this never so-quite clear ideal has been joined by another and much more demanding one – global peace. In that sense, international law has been gradually formed, through which efforts are being made to institutionally guarantee the realization of the legal prohibition of wars. Achieving, or at least approaching global peace and / or security, is possible only through the cooperation of independent and legally equal states – members of the international community. The only institutional framework for that cooperation is the UN. If the UN does not work, ie. if it is not effective, then there is no peace, no “international security”, just as there is no freedom or human rights. The future of global security, ie. world peace depends on the ability of the UN to restrain, even in principle, the powerful states of the world in their “natural” ambitions to unilaterally impose their political will and interests. If the UN does not find an effective way to do that, its survival will be in question, and if it disappears, the future of all of us is undoubted and certain – a catastrophe in continuity.
