The primary role of the United Nations (UN) in international conflict resolution after World War II was to serve as a platform for diplomatic dialogue and peacekeeping. Established in 1945, the UN sought to prevent future conflicts through collective security, negotiation, and mediation between nations. The organization deployed peacekeeping forces in various regions to stabilize situations and protect civilians. It also implemented programs aimed at fostering development, humanitarian aid, and the promotion of human rights. The UN's efforts represent a multifaceted approach to resolving conflicts and maintaining international stability in the post-war world.
