"Peace and security" refer to the state of tranquility and safety within a community or nation. Peace involves the absence of conflict, violence, or war, allowing individuals to live without fear. Security, on the other hand, encompasses measures taken to protect people and property from threats, ensuring stability and order. These concepts are often linked to international relations, where organizations like the United Nations work to promote peace and security globally. Efforts may include conflict resolution, peacekeeping missions, and disarmament initiatives, all aimed at fostering a safer environment for all nations and their citizens.
