It is now generally accepted that the global order is shifting, but the literature is divided on how. Consequently, it is not surprising that there is a lack of strong scholarship on the characteristics of the order from a Central and Eastern European (CEE) perspective. Therefore, this article aims to explore the future of the Liberal World Order (LWO) from this perspective through the lens of mainstream theories. The article looks at the geopolitical dynamics of the region and the evolving strategic perceptions of the LWO. It examines how CEE, traditionally seen as the frontier of the LWO (EU and NATO), is navigating the complexities of the current global political landscape in the light of the changing order. The second part of the article specifically analyses the security perceptions of CEE governments. The article seeks to contribute to the understanding of the future trajectory of the LWO, the potential implications for global peace and security, and the interplay of realism and liberalism in shaping our understanding of this trajectory from the CEE perspective.
