U radu se, korištenjem konstruktivističkog pristupa Alexandera Wendta, analiziraju razlozi za nastanak europskih integracija s obzirom na neriješeno njemačko pitanje. Pritom se koristi model odnosa identiteta i interesa kako bi se analiziralo ponašanje Sjedinjenih Američkih Država i Sovjetskoga Saveza u razdoblju od 1945. do 1990. s obzirom na nastanak hladnoga rata, europskih integracija i rješavanje njemačkoga pitanja. Također se analizira odnos identiteta i interesa dviju njemačkih država prema njihovom budućem ujedinjenju. Polazeći od Giddensove teorije strukturacije, na koju se naslanja Wendtov konstruktivizam, prati se ponašanje države kao agenta u odnosu prema anarhiji kao strukturi među‑ narodnog sustava. U članku se propituje pretpostavka da je neriješeno njemačko pitanje ubrzalo, ali i uvjetovalo nastanak europskih integracija. Na kraju članka analizira se utjecaj politike detanta i njezinih posljedica na njemačko ujedinjenje. In this article, Alexander Wendt’s constructivist approach was used in order to explain the reasons for the formation of European integrations in regard to the unresolved German Question. The model of interaction between identities and interests was used in order to analyse the behaviour of two superpowers between 1945 and 1990, in relation to the following developments: the Cold War, European integrations, and German unification. The behaviour of two German states regarding their future unification was also observed. The state was used as the basic unit of analysis. As theoretical foundation, Wendt’s constructivist approach, which rests on Giddens’ theory of structuration, was used in order to explain duality of structure and agency in relation to reproduction or transformation of the (international) system. The assumption that the unresolved German Question not only accelerated but also conditioned the emergence of European integrations, was put under scrutiny. It was also analysed how the emergence of the policy of detente conditioned the changes in international relations during the observed period, particularly in regard to ideational factors such as the results of the Conference on European Security and Cooperation, West German Ostpolitik, and the appearance of new ideas in the former Soviet Union, as well as their role in the unification of two German states in 1990.
