The UN Isn’t Declining. It’s Decomposing.

Carnegie Endowment for International Peace | Stewart Patrick, Theodore Zaritsky

The United States under President Donald Trump is accelerating the decomposition of the United Nations by selectively defunding and bypassing its core peace and security functions. This transactional approach, which includes slashing humanitarian aid by four-fifths and withholding billions in peacekeeping dues, threatens to permanently fracture the postwar multilateral order.

Historically, Washington has relied on the UN Security Council for international legitimacy, but current policies increasingly outsource operations to non-UN coalitions in places like Haiti and Somalia. Great power obstruction has already crippled the Security Council's legislative capacity, driving interstate conflict to an eighty-year high. The institution is fracturing. Consequently, middle powers are now bypassing the central apparatus to broker independent, bilateral security arrangements, leaving the General Assembly to assume the remaining strain as the broader system fragments. With the United States owing approximately $4 billion in arrears, the organisation faces imminent financial collapse.

Comment

The outsourcing of security mandates to coalitions like the Gang Suppression Force in Haiti signals a structural breakdown in unified command and control. By bypassing traditional UN-commanded blue-helmet frameworks, the UN Security Council is transitioning from an operational headquarters into a mere political clearinghouse. This shift dilutes standardised rules of engagement and removes centralised oversight, as seen in the funding disputes plaguing ATMIS in Somalia. Consequently, operations like the Multinational Security Support mission in Haiti are left to rely on fragmented coalition logistics rather than cohesive UN Department of Peace Operations doctrine.

This command fragmentation mirrors the operational collapse of UNPROFOR in Bosnia during the 1990s, where a dual-key command structure paralysed decision-making. The subsequent transition to the NATO-led IFOR demonstrated that effective enforcement requires a unified, non-UN military command rather than a compromised Secretariat hierarchy. Ultimately, the reliance on the Kenyan-led mission in Port-au-Prince confirms that the UN Security Council is reverting to this historical pattern of delegating tactical authority to avoid its own structural paralysis.

Strategic Question for Discussion

Which carries more operational risk for future multilateral interventions—the command fragmentation seen in the Kenyan-led mission in Port-au-Prince, or the political paralysis that historically crippled UNPROFOR in Bosnia—and what does this balance reveal about the limits of modern coalition-based peacekeeping?

The available evidence points toward command fragmentation carrying the greater immediate operational risk, as ad-hoc coalitions lack the institutionalised logistics and standardised rules of engagement of established alliances. While political paralysis at the UN Security Council delays deployment, the tactical friction experienced by the Kenyan-led mission in Port-au-Prince suggests that non-integrated command structures ultimately jeopardise force protection and mission success on the ground. Consequently, the trajectory indicates that bypassing the UN's formal structures yields rapid deployment at the cost of long-term operational viability.
