Small states shelter diplomacy: Balancing costs of entrapment and abandonment in the alliance dilemma

Shelter theory has emerged as a promising but unrealized alternative to existing theories of bandwagon and hiding in the literature. It describes how small states can utilize the structural power of great powers to achieve political aims through the formation of asymmetric alliances. At present it is not clear exactly what shelter diplomacy aims to achieve, what type of costs it protects small states against and to what degree asymmetric shelters are useful when the preferences between the small state and the shelter partner widen. The article addresses these gaps. It develops a realist inspired model of shelter diplomacy that specifies when, how and with what effects small states can utilize the structural powers of great powers. It demonstrates how shelter diplomacy can help small states balance the costs of abandonment and entrapment in the alliance dilemma through construction of both asymmetric and symmetric shelters. The main contributions are to bring shelter diplomacy into the International Relations mainstream literature and develop a new theoretical middle position between the more well-described bandwagon and hiding strategies. The model is applied to a Danish case that demonstrates how small states have utilized and adopted dynamic shelter strategies in the European integration process.
