Abstract
The Security Council is usually considered as the most important organ of the UNO. Primarily "responsible for the maintenance of international peace and security" , the Security Council has huge responsibilities and thus needs legitimacy to fulfill its mission. There has been a great demand for a reform of the UN, and one of the greatest challenges is the reform of the Security Council, which would be "a decisive test of its capacity for comprehensive reform of any kind." However, no reform has been successfully implemented yet and it is therefore necessary to analyze both the reasons why this organ should be reformed and what the various solutions might be.Why should we reform the UN Security Council? Since its foundation in San Francisco in June 1945, the UN Security Council has only been reformed once: that was in 1965, when the General Assembly adopted an amendment extending the size of the Council from 11 members (5 permanent and 6 non-permanent) to 15 (with 4 new non-permanent members). The two other important changes were the replacement of Taiwan by the Popular Republic of China in 1971 and of the dissolved USSR by the Russian Federation in 1991.
