The United Nations Security Council is experiencing severe operational paralysis as intense great-power rivalry and frequent vetoes by major powers undermine its authority during conflicts in Ukraine and Gaza. This gridlock is compounded by substantial funding cuts and alternative political forums established by the Trump administration, directly jeopardising the global body's peace preservation mission.

To contextualise these existential challenges, a new PRIF Working Paper traces the long-term evolution of the institution's core policy instruments across the critical domains of peacemaking, peacekeeping, and peacebuilding. The study systematically surveys major academic and policy debates surrounding structural reform, illustrating how deep-seated geopolitical divisions have transformed the council into a mere echo chamber of international crises. Ultimately, these compounding financial constraints and diplomatic blockages force a critical reassessment of the organization's future trajectory, highlighting the severe escalation risks and unresolved tensions that threaten its capacity to maintain international peace and security.

Comment

The paralysis of the United Nations Security Council shifts the operational burden of international security enforcement away from collective security doctrines toward minilateral coalitions. This doctrinal decay is most visible in the bypass of traditional peacekeeping mandates in favour of ad-hoc security architectures, similar to the multinational missions authorised outside direct Chapter VII oversight. Consequently, the historical reliance on General Assembly Resolution 377A, or the Uniting for Peace mechanism, increasingly serves as a diplomatic protest tool rather than an effective enforcement alternative. This shift signals a transition where regional security arrangements, such as those under Article 51, supersede universalist security frameworks.
