Explanation – The most significant power India would gain with permanent membership in the United Nations Security Council (UNSC) is veto power over substantive resolutions. Permanent members of the UNSC, known as the P5 (China, France, Russia, the United Kingdom, and the United States), have the power to veto any substantive resolution. This means they can block any decision or action proposed by the Council, regardless of international support. Gaining veto power would allow India to have a decisive influence on international peace and security decisions.
