The United Nations was set up in the backdrop of Second World War which represents the liberal model of collective security. It has been successful in decolonization process and preventing another world war. The United Nations seeks to prevent the successive generation from the scourge of war. The UN Charter established UNSC (United Nations Security Council) as one of the six main organs of UN (United Nations). The major responsibility of UNSC is to maintain international peace and security. The membership in UNSC constitutes with 15member countries, of which 5 are Permanent members and 10 as temporary members. The UNSC is the only body in the UN which has teeth to bite. It has the power to make decisions that member countries are obligated to implement under the Charter. With rapidly changing geopolitics of the present 21st century, it becomes imperative that reform is needed in the UNSC as today, the global politics has been marred with structural changes like threefold increase in the world population, decentralization of powers, a shift in material power of the state and influence from the West to the East with multi-polarity transition.
