In this wide-ranging discussion, Professor Peter J. Hoffman argues that the United Nations’ current paralysis reflects a deeper crisis of legitimacy rather than a temporary political impasse. He examines why incremental reform is no longer sufficient, probing core questions of Security Council authority, democratic representation beyond states, the governance of planetary risk, and the constitutional status of human rights. Drawing on historical experience with institutional change, Hoffman situates the Second UN Charter between realism and ambition, contending that transformative reform often appears unrealistic until conditions make its necessity undeniable. As he concludes, what is dismissed today as idealism may, with the passage of time, come to be seen as the most realistic response to a system no longer fit for purpose.
