From Collective to Transactional Defense

This article aims to highlight the most important changes within the transatlantic defense relations. The central argument is that NATO is gaining a conditional nature, transforming collective defense into a form of transactional defense. The study utilizes Paul Kennedy's notion of "imperial overstretch" to explain the strategic context of the transatlantic defense relations. After this, the analysis highlights how the transatlantic defense relations gained a transactional character that is resonating to this American "imperial overstretch". The second part of the study focuses on the latest developments concerning the US military presence in Europe and highlights their transactional character, thus enabling the emergence of transactional defense within NATO.
