We have, built up an impressive record of peacekeeping achievements over more than 70 years of our existence, including winning the Nobel Peace Prize. Since 1948, the UN has helped end conflicts and foster reconciliation by conducting successful peacekeeping operations in dozens of countries, including Cambodia, El Salvador, Guatemala, Mozambique, Namibia and Tajikistan. UN peacekeeping has also made a real difference in other places with recently completed or on-going operations such as Sierra Leone, Burundi, Côte d’Ivoire, Timor-Leste, Liberia, Haiti and Kosovo. By providing basic security guarantees and responding to crises, these UN operations have supported political transitions and helped buttress fragile new state institutions. They have helped countries to close the chapter of conflict and open a path to normal development, even if major peacebuilding challenges remain.
