Beyond Dues: The Role of U.S. Military Aid in UN Peacekeeping Operations

ABSTRACT Shortfalls in personnel are common across UN peacekeeping operations (PKOs). An ongoing concern is that many PKOs lack sufficient resources to effectively fulfil their mandates. This may in turn be a major contributing factor to shortages of peacekeepers. How do provisions of non-personnel resources to UN PKOs shape other states’ voluntary commitments of peacekeeping personnel? This study focuses on the role of the U.S.’s voluntary peacekeeping assistance as a mechanism for reducing personnel shortfall. By providing additional assistance for specific peacekeeping operations, the U.S. enhances the ability of states that are willing but lack the resources to deploy peacekeepers and increases the willingness of states that are otherwise reluctant to make personnel commitments to these operations. In turn, these provisions of support lead to greater personnel commitments to the missions where the U.S. allocates this aid. Results from an analysis of U.S. peacekeeping assistance and personnel commitments within UN operations from 2000 to 2015 indicate that these aid provisions lead to reductions in shortfalls of peacekeepers. These findings suggest that the U.S. not only increases collective personnel commitments by providing this additional assistance but, in doing so, may also enhance the effectiveness of the missions it supports.
