What was the purpose of the United Nations? First, it was to safeguard peace and security. Second it was to restore faith in human rights. Third, to uphold respect for international law. Finally, the UN wanted to promote social progress and better standards of living. The Introductions asks: has the UN been able to achieve all, some, or any of these goals? The UN might not have quite lived up to the hopes of its founders but it is the only truly global organization in history. The UN might be deeply flawed and in need of reform but it is still needed.
