The limit of American public support for military intervention

In: Armed forces & society

Abstract

Under what conditions is the American public supportive of U.S. military intervention in foreign crises? We argue that the public assesses three key dimensions of an intervention: the motivation for an intervention, the form an intervention can take, and the tasks an intervention may be mandated to fulfill. Through a survey experiment, we test several hypotheses in the context of a potential U.S. military intervention in a civil war. Comparing different motivations, we find that the strategies (forms and mandates) matter much more for public support. Regardless of motivation, the American public is generally more supportive of multilateral forms of intervention and prefers mandates that focus on the protection of civilians and peaceful conflict resolution.
