This article analyses the challenges and perspectives of the European Union's security and defence policy in a new geopolitical era shaped by Russian aggression against Ukraine, growing US-China rivalry, and instability in the EU's neighbourhood. It identifies three key weaknesses that limit the Union's strategic autonomy: insufficient military capabilities, the fragmentation of the defence industry, and a reliance on external suppliers of weapons, equipment, and critical raw materials. Drawing on an interdisciplinary framework that combines political economy, political science, European studies, and security studies, the article examines how existing tools and initiatives, the EDF, PESCO, ASAP, EDIRPA, and the ReArm Europe plan, are responding to these deficits. While these instruments and initiatives demonstrate the EU's ambition to strengthen its security role, their effectiveness remains limited by political divergences and restricted resources. The author concludes that overcoming fragmentation and building sustainable mechanisms for defence cooperation are essential if the EU is to establish itself as a credible security actor in a multipolar world.

This paper explores the potentialities and constraints of building the European Union's strategic autonomy in a new geopolitical era marked by the rivalry between the United States and China, the weakening of the multilateral order, and the consequences of the war in Ukraine. The authors primarily focus on the political, economic, and technological dimensions of autonomy, utilising relevant scientific methods within an interdisciplinary research framework, primarily the analytical-synthetic method, content and comparative analysis, as well as the scenario approach. The findings indicate that the EU is capable of progressively reducing its dependency through the diversification of resources, investments in development, research, and innovation, and the strengthening of digital and technological sovereignty. Simultaneously, however, the Union faces serious limitations, the fiscal constraints of the Member States, the fragmentation of its foreign and security policy, and a persistent reliance on the United States in the area of defence. The EU’s future position will therefore hinge on its ability to consolidate its economic and technological potential and transform it into a unified political will and a credible geopolitical power.

The current geopolitical changes and the dedication to regional safety have drawn researchers’ attention towards discussion on the multiple aspects of new residents’ integration. Ensuring that new members of society are welcomed has been of significant scientific and political interest in sustaining coherent and resilient communities. This discussion also extends to the well-being of soldiers and their families when relocating due to deployment. Since deployment locations vary, the state of scientific knowledge highlights the need to investigate the integration of soldiers and military-related families within the specific contexts of individual states. Accordingly, this study examines the case of Lithuania, with a focus on the socio-legal factors influencing the integration of military-related families. The research is based on a thematic analysis of international scientific literature, identifying the main challenges faced by families residing in foreign countries. It also outlines the conditions necessary for the successful integration of military-related families in the Lithuanian context. The findings indicate that: a) in addition to traditional integration programs, special attention must be given to the specific characteristics of military life; b) integration of military-related residents should adopt a family-centred approach that considers the past, present, and future experiences, needs, and aspirations of family members; and c) successful integration requires strong intersectoral cooperation. The practical implications highlight the need for practitioners to pay particular attention to monitoring and managing both the sequence and quality of the integration of foreign soldiers’ families during their residence in the host country.
