Resisting troop reductions: How downsizing burdens are allocated as UN peacekeeping contracts

UN peacekeeping is shrinking. Total uniformed personnel deployments fell by 43% between their 2015 peak and 2025. As missions close or draw down, UN troop demand increasingly falls below supply. In this context, troop contributing countries’ (TCCs’) motivation – the focus of most existing literature – no longer adequately explains deployment patterns. This article theorizes that three factors may shape which motivated TCCs preserve their deployment: operational utility; large TCCs’ influence; and UN commitment to broad participation. Using updated troop contributions data (2010–2024) and 23 interviews with UN officials, this article examines contemporary patterns of contraction overall and in six major downsizing missions. It finds that both top and token troop contributors are relatively shielded from downsizing, shifting the burden to mid-size TCCs. Standard troop quality measures do not predict downsizing patterns, suggesting the need for more nuanced understandings of operational utility and its role in the politics of UN force generation.
