Personal Details

Dianne Pfundstein Chamberlain’s new book, Cheap Threats: Why the United States Struggles to Coerce Weak States (Georgetown University Press, 2016) explores why weak states resist compellent threats issued by the world’s sole superpower. It argues that the United States struggles to coerce weak states because it has developed a war-fighting model that renders the use of force relatively cheap, and thus the threat to use force does not effectively signal a high level of motivation to target states. The book presents a new dataset on U.S. compellent threats in crises 1945-2007 and four cases in which the United States issued a compellent threat against a weak state.

Pfundstein Chamberlain is currently working on a manuscript about democracy and decision-making during the Second World War. The book draws on archival research she has conducted in the United Kingdom and France. She also writes a blog about security policy and theory, On Security ( Her work has appeared online with The National Interest (
