Peacekeeping is defined by the United Nations as ways to help countries torn by conflict create conditions for sustainable peace. UN peacekeepers are also known as Blue Berets, "monitor and observe peace processes in post-conflict areas and assist ex-combatants in implementing the peace agreements they may have signed." UN peacekeepers will provide assistance in the form of confidence building measures, power sharing arrangements, electoral support, strengthening the rule of law, and economic and social development. Blue berets consist of soldiers, civilian police officers, and other civilian personnel. The United Nations Charter gives the Security Council the power and responsibility to take action to maintain international peace and security, therefore if UN peacekeepers are sent anywhere; it will be at the request of the Security Council.
UN peacekeepers are mostly sent to operations that have already been developed and implemented by the organization itself, and the troops serve under the UN. Peacekeepers should not be confused with soldiers, as their primary role is not to fight. Blue Berets help facilitate the peace process after it has already been established. Though UN peacekeepers are now armed, it was not the case initially which as a great deal to do with their duties and the nature of their work.
In Asia, UN peacekeepers were sent in the late 1980s during the Soviet invasion of Afghanistan, and most recently between years 2002-2005 to East Timor due to Indonesian invasion and occupation. In Europe, there were plenty of Blue Berets sent to the Balkan States such as the former Yugoslavia and Bosnia in the 1990s. Also in the 1990s, Blue Berets helped maintain peacekeeping operations in Croatia after they had gone through a war.
