This article asks why Denmark and Estonia have eagerly attempted to ‘punch above their weight’ in the transatlantic relationship since the end of the Cold War and shows how they differ in their strategies to do so. Using neoclassical realism as a

the two countries. Following this analysis, we discuss the future of super atlanticism.
