Since the end of the Cold War, the UN has been engaged in a substantial, and largely successful, intensification of efforts to resolve longstanding conflicts throughout the world. The UN operations in Namibia, Cambodia, Mozambique and El Salvador are regarded as particularly successful. However, there have been other UN operations which did not fully achieve their objectives. The UN is now applying the lessons of these operations. For example, in the light of its investment in Somalia, the UN is taking a more cautious approach to peace enforcement action under UN command and more attention is being given to peace-keeping in its traditional form to which Ireland has contributed substantially over the years. New attention is also being paid to conflict prevention and the mechanisms for early warning.
The United Nations peace-keeping presence in Bosnia-Hercegovina, Croatia and the former Yugoslav Republic of Macedonia, has been the largest UN peace-keeping mission to date. The Security Council deployed UNPROFOR to alleviate the impact of war on the civilian population; to contain the conflict and to mitigate its consequences.
UNPROFOR worked, in the most difficult of circumstances, to create a climate conducive to the negotiation of an overall settlement. The presence of the United Nations peace-keeping forces and the UNHCR and other humanitarian and relief agencies to which they afforded protection, has been invaluable in saving many thousands of lives. For example, the UN is currently providing humanitarian assistance for 3.6 million people in former Yugoslavia.
In Croatia, the deployment of the UN peace-keeping force brought an end to the Serbo-Croat war in 1991, and relief to the victims of the conflict. It was instrumental in reducing the possibilities for a new Serbo-Croat war. The small United Nations peace-keeping presence in the former Yugoslav Republic of Macedonia has helped prevent the conflict spilling over. This has been a most effective exercise in preventative deployment by a UN peace-keeping operation.
