The United Nations Security Council is one of the six main United Nations bodies, primarily responsible for maintaining international peace and security. It is comprised of fifteen member countries. Five are permanent members with veto power: the Russian Federation, China, the United Kingdom, France and the United States. The other ten are non-permanent members elected for two-year terms by the General Assembly. Currently, those countries are: Argentina, Azerbaijan, Australia, Guatemala, Luxembourg, Morocco, Pakistan, Republic of Korea, Rwanda, and Togo. The Security Council is the only organ of the United Nations that has the power to make decisions that member states are obligated to implement. The UNSC can undertake investigations, dispatch missions, send envoys, enforce economic sanctions, organize blockades, and authorize military operations, among other things. Their work continues to be fundamental in the development of international affairs.
