Birds of a Feather, Do Sanctioned States Flock Together?

Despite several high-profile cases of cooperation between sanctioned states, little is understood about how being sanctioned affects target states' incentives to cooperate with one another and what forms that cooperation might take. I theorize that sanctioned states will tend to seek out sanctions-surviving assistance from nonsanctioned states in most cases. Being sanctioned constrains how much useful assistance that sanctioned states can provide to one another, as they suffer from similar trade constraints, levels of economic turmoil, and governmental resource limitations. I test my theory's predictions that sanctioned states are less likely to cooperate with one another via two different large-n tests involving cooperation via engaging in trade-based sanctions-busting and civil nuclear cooperation. Both of these distinct tests provide strong support for my theory. The final portion of the study conducts an exploratory analysis of why sanctioned states still sometimes cooperate with one another, finding that such cooperation may involve risky or taboo transactions, like arms sales, and that sanctioned parties have incentives to keep their cooperation a secret in such cases. These findings improve our understanding of the various cooperative strategies that states employ to survive sanctions.
