Abstract

The United Nations Security Council (UNSC) remains an important source of legitimacy for international action. Yet despite dramatic changes in the international system over the past forty-five years, the composition of the UNSC has remained unaltered since 1965, and there are many who question how long its legitimacy will last without additional members that reflect twenty-first century realities. There is little agreement, however, as to which countries should accede to the Security Council or even by what formula aspirants should be judged. Reform advocates frequently call for equal representation for various regions of the world, but local competitors like India and Pakistan or Mexico and Brazil are unlikely to reach a compromise solution. Moreover, the UN Charter prescribes that regional parity should be, at most, a secondary issue; the ability to advocate and defend international peace and security should, it says, be the primary concern.
