Challenges to national defence in contemporary geopolitical situation

This paper critically analyses the escalating security challenges facing the European Union, primarily defined by the Russian Federation's military aggression against Ukraine after 2022 and the return of great power tensions. This transformation of the security environment has definitively ended the era of post-conflict peace on the European continent and exposed deep structural vulnerabilities in assuring sovereign European defence. The analysis identifies three key structural challenges: the critical fragmentation of Member States' defence capabilities and capacities, the limited ability to respond to high-intensity conflict, and the industrial unpreparedness of the European Defence Technological and Industrial Base. It is asserted that the EU’s persistent reliance on external guarantees, particularly amid rising transatlantic uncertainty, jeopardises its political sovereignty. To overcome these structural limitations, the paper advocates for a deeper integration trajectory towards the concept of a Total Defence Union. It posits that strengthening European defence is a strategic imperative for maintaining Europe's stability and international standing in an era of increasing great power rivalry.

The paper presents the results of a sectoral analysis of the Czech Republic’s security environment and interprets them from the perspective of strategic studies. Its objective is to identify key structural trends shaping the operational and strategic environment and to derive their implications for defence planning, capability development, and the long-term transformation of the Armed Forces of the Czech Republic. The analysis shows that the security environment in last years is characterized by persistent geopolitical instability and accelerating technological change. The rapid diffusion of unmanned systems and artificial intelligence applications is transforming the conduct of warfare and increasing demands for capability modernization, interoperability, and force readiness. At the same time, demographic and societal pressures are deepening, affecting the personnel sustainability of the armed forces and the overall strategic resilience of the state. Economic and environmental factors intensify competition for resources and raise demands for the prioritization of defence investments. The findings confirm the growing interdependence of sectors and the necessity of integrated assessment of the security environment as a foundation for force and capability development.

Our paper focuses on the threats to the global development and sustainable economic development of a country that might include economic, political, human development, as well as sustainable development issues and problems. Sustainable economic development might serve as a tool for fostering the country’s prosperity and helping it to overcome various threats that might stem from its geolocation, economic situation, natural resources, as well as many other internal and external factors that all play their decisive roles. The paper uses a case study of the United States as an example of the country vulnerable to a plethora of threats. It analyzes the most crucial threats one by one and classifies the most notorious and impending issues stemming from these threats that might hamper the economic growth and development. In particular, we focus on the issue of energy security and the renewable energy sources (RES) that represent an important aspect in this debate and research. Our results can be used by the policymakers as well as regional development managers for improving the security strategy.

Since demographic problems have appeared, the pension system’s transformation has become an extremely relevant issue in terms of dealing with country’s social security problems. Development of medicine and a better quality of life have caused population aging which is particularly noticed in the developed countries.

Therefore, the article analyses the sustainability of Lithuania II pillar pension funds using multi-criteria methods. The carried out research has enabled the evaluation and comparison of II pillar pension funds and their performance. The use of multi-criteria methods combining a few funds’ actions defining indicators into a whole have helped to evaluate the pension funds. In addition, it has helped to identify the funds’ operational sustainability and to choose the best fund, emphasizing the most important aspects for each member and shaping the weights of multi-criteria methods’ evaluation. It is important to emphasize that the aspect of reward indicator is significant in the asset accumulation in pension funds because the goal of these funds is to accumulate the biggest amount of asset for the future pension in a long period and not just to protect the money from its depreciation. Finally, it is worth mentioning that this type of a research provides a new perspective on the pension funds’ evaluation in the context of other criteria.
