The Security Council is the United Nations' most powerful body, with "primary responsibility for the maintenance of international peace and security." Five powerful countries sit as "permanent members" along with ten elected members with two-year terms. Since 1990, the Council has dramatically increased its activity and it now meets in nearly continuous session. It dispatches military operations, imposes sanctions, mandates arms inspections, deploys election monitors and more.
