Abstract: In this article, we present the results of two survey experiments on public support for nuclear, chemical, and conventional strikes. We examined how moral values of individuals interact with the approval of different kinds of strikes and with the effects of information about the ingroup and out-group fatalities. Our results show that while the public is more averse to the employment of chemical weapons than to the conduct of nuclear or conventional strikes, the overall relationship between strike approval and the individuals’ moral values does not differ across the three experimental treatments. In addition, we found that individuals’ scores in so-called “binding” moral values affect the sensitivity of the public for in-group fatalities. Findings of our paper contribute to the broader debates in the field about the strength and nature of the norms against the use of nuclear and chemical weapons, and about the role of morality in the public attitudes to the use of military force.
