The organization responsible for maintaining international peace and security is the United Nations (UN). Founded in 1945 after World War II, the UN aims to prevent conflicts, promote cooperation among nations, and provide a platform for dialogue. Its pivotal component in peacekeeping efforts includes deploying peacekeeping missions in conflict zones to help stabilize regions and protect civilians. The Security Council, a key branch of the UN, is tasked with addressing threats to international peace and can impose sanctions or authorize military interventions in response to aggression or violations of international law.
