It seems, often, policymakers send disaster relief personnel and resources into dangerous situations without a clear explanation of the mission's application to US national interests. So, what is the purpose of air-enabled disaster assistance missions? And, to what extent are these missions successful at meeting intended outcomes? Answers to, or a better understanding of, these questions are needed now more than ever considering the looming problem of climate change that will likely animate more calls for American aid. Using quantitative and qualitative analysis of 31 disaster assistance cases between 19922017, this research attempts to add rigor and breadth to policy reviews of foreign relief operations with positive interstate relations as an outcome. This research finds inconclusive evidence that disaster assistance missions positively influence interstate relations.
