Losing on the home front? : battlefield casualties, media, and public support for foreign interventions

How domestic constituents respond to signals of weakness in foreign wars remains an important question in international relations. This paper studies the impact of battlefield casualties and media coverage on public demand for war termination. To identify the effect of troop fatalities, we leverage the timing of survey collection across respondents from nine members of the International Security Assistance Force in Afghanistan. Quasi-experimental evidence demonstrates that battlefield casualties increase the news coverage of Afghanistan and the public demand for withdrawal. Evidence from a survey experiment replicates the main results. To shed light on the media mechanism, we leverage a news pressure design and find that major sporting matches occurring around the time of battlefield casualties drive down subsequent coverage, and significantly weaken the effect of casualties on support for war termination. These results highlight the role that media play in shaping public support for foreign military interventions.
