How do nuclear weapons affect interstate conflict? Empirical studies on this question have returned mixed results. We argue that these results are due to overlooking indirect conflicts, a distinct and prominent form of limited conflict. Expanding current datasets to account for both conflict intensity and directness provides new insights about interstate conflict. We investigate the relationship between nuclear weapons and conflict through a large-n analysis that includes a new indicator for indirect conflict. We find that state dyads which possess nuclear weapons are significantly more likely to engage in indirect conflict. The results suggest the importance of including measures of indirect conflict in future scholarship and the need for policymakers to prepare for increased instances of indirect conflict between major powers possessing nuclear weapons.
