| Summary/Abstract |
We examine how a great power’s past behavior toward an informal security partner affects the broader credibility of its security commitments, focusing on the implications of America’s dramatic troop withdrawal from Afghanistan in 2021 as perceived by the U.S., South Korean, and Chinese publics. Against conventional wisdom, we show that knowledge about a great power’s decision to abandon an informal partner in one region of the globe can help increase confidence about its alliance commitments elsewhere. Our survey experiments identify a striking disjuncture: Although Americans tend to believe that the abandonment decision in Afghanistan will hurt their country’s credibility in East Asia, no such effect is found in South Korea and China. In fact, East Asian respondents who are reminded of the Afghanistan withdrawal become more confident about American security commitments when alerted to the possibility that this decision will help Washington to concentrate additional military capabilities in their region.
