Theoretical and practical structure of the power system behind the implementation of the global powers’ foreign and security policies should be analysed with the postmodern understanding. In this context, after understanding the modern and postmodern hegemony, the global powers’ hard and soft power interests are crucial elements of democracy development and crisis management within the network strategy in Balkan policies. The security culture is about states’ security perception, which actors are effective in the process which tools are used to combat threats. According to postmodern geopolitics, the Post-Cold War with the axis of global powers, and Balkan policies of these powers are related with the development of political changes. United States (US) maintains its military superiority in the world order with state actors, and on the other hand, cooperates with the European Union (EU) as an international organization. According to the post-modern understanding, there is neither a new world order nor a new world disorder in the world today. Instead, there is a security zone in Europe and a zone of danger and chaos outside. Balkan policies of global powers are essential because of the problematic issues in the region. Balkan geography constitutes a critical equation in this regard. In this study, it is evaluated that EU democracy development projects are different from US in terms of strategy and institutional means. Some of the projects are considered within the EU's enlargement strategy, while others are considered as a foreign policy strategy, which is mainly assumed by the leading countries as China. Compared to the US, the EU strategy focuses more on non-military operations, and Balkan policies of these states are a clear case in postmodern geopolitics.
