Restorative Justice methods. Many of those studying the success of these methods, including a United Nations working group on Restorative Justice , have attempted to re-define justice in terms related to peace. From the late 2000s on, a Theory of Active Peace has been proposed which conceptually integrates justice into a larger peace theory. Another internationally important approach to peace is the international, national and local protection of cultural assets in the event of conflicts. United Nations, UNESCO and Blue Shield International deal with the protection of cultural heritage. This also applies to the integration of United Nations peacekeeping. UNESCO Director General Irina Bokova stated: "The protection of culture and heritage is a humanitarian and security policy imperative that also paves the way for resilience, reconciliation and peace." The protection of the cultural heritage should preserve the particularly sensitive cultural memory, the growing cultural diversity and the economic basis of a state, a municipality or a region. In many conflicts there is a deliberate attempt to destroy the opponent's cultural heritage. Whereby there is also a connection between cultural user disruption or cultural heritage and the cause of flight. However, protection can only be implemented in a sustainable manner through the fundamental cooperation and training of military units and civilian personnel, together with the locals. The president of Blue Shield International Karl von Habsburg summed it up with the words: “Without the local community and without the local participants, that would be completely impossible”. Organizations and prizes United Nations The United Nations (UN) is an international organization whose stated aims are to facilitate cooperation in international law, international security, economic development, social progress, human rights, and achieving world peace. The UN was founded in 1945 after World War II to replace the League of Nations, to stop wars between countries, and to provide a platform for dialogue. After authorization by the Security Council, the UN sends peacekeepers to regions where armed conflict has recently ceased or paused to enforce the terms of peace agreements and to discourage combatants from resuming hostilities. Since the UN does not maintain its own military, peacekeeping forces are voluntarily provided by member states of the UN. The forces, also called the "Blue Helmets", who enforce UN accords are awarded United Nations Medals, which are considered international decorations instead of military decorations. The peacekeeping force as a whole received the Nobel Peace Prize in 1988. Police
