The Big Problem of Small Allies: New Data and Theory on Defiant Local Counterinsurgency Partners in Afghanistan and Iraq

Alliance politics are critical yet understudied in counterinsurgency interventions. Despite the importance of local allies, traditional research on alliances fails to account for the challenges of managing in-country counterinsurgency security partners or explain variation among which types of policy requests from large intervening allies are likely to result in compliance or defiance by local partners. When did US intervening forces have leverage in Iraq and Afghanistan, and when was American influence limited? Utilizing thousands of US government documents to analyze over 250 US demands of allies in Kabul and Baghdad, this paper reexamines established variables in the literature on inter-alliance bargainingnamely allied interests and dependenciesto offer a new model describing the interaction of these variables in asymmetric counterinsurgency partnerships. The theory predicts when large allies are likely to influence local partners and when these intervening forces will likely fail to coerce them.
