The second decade of the 21st century brought Poland a range of complex challenges in the field of national and international security. Key factors included shifts in the geopolitical environment following Russia’s aggression against Ukraine in 2014, increased NATO activity on the eastern flank, and the growing importance of hybrid, cyber, and energy-related threats. Poland also faced the need to modernize its armed forces and strengthen state resilience to migration and information crises. The paper analyses the main directions of these challenges and presents the measures undertaken in response, highlighting Poland’s role as a key security actor in the Central and Eastern European region.

This paper examines how new security technologies could reshape Bulgaria’s critical infrastructure resilience while simultaneously creating new vulnerabilities and dependencies. Bulgaria’s modernization, pursued through EU and NATO frameworks and supported by initiatives such as the Defense Innovation Center, promises stronger protection against evolving threats. Yet these same pathways embed risks, from reliance on external vendors and standards to design-level weaknesses such as expanded cyber attack surfaces and system complexity. Adopting a prospective, scenario-oriented approach, the paper argues that resilience and dependency develop in parallel, and that anticipating this paradox will be essential for shaping Bulgaria’s future security strategy.

This paper examines the prospective role of Bulgaria’s newly established Defense Innovation Center at Sofia Tech Park in strengthening critical infrastructure resilience. Designed in line with NATO and EU standards, the Center is expected to test emerging technologies and develop prototypes, with an initial focus on unmanned aerial vehicles (UAVs) and advanced defense systems. The analysis adopts a conceptual approach, outlining potential applications of these dual-use technologies across the energy, communications, cyber, and transport sectors. It also highlights key risks, including funding sustainability, dual-use dilemmas, and continued dependence on external technological ecosystems. By situating the initiative within the broader NATO and EU innovation landscape, the paper underscores both the opportunities and uncertainties of integrating defense-driven innovation into national resilience strategies.

NATO is facing an array of challenges in the Balkans – both ‘old’ and conventional, and ‘new’ and asymmetric. This paper seeks to offer an overview and provide an analysis of the risks emanating from Russia’s strategic interests in the peninsula and possible complications as an example of ‘traditional’ threat. Additionally, the author will strive to a nalyze them in the context of ‘modern’ security challenges in the region, such as the risks stemming from the migration from the Middle East and North Africa, and the challenges, particularly in the Western Balkans, of radicalization and returning foreign fighters. NATO’s role in the region is particularly important as no single country in the region has the capabilities to address such transnational threats and challenges unilatera lly. The hypothesis is that the Alliance needs to significantly enhance its soft power capabilities, intensify cooperation between stakeholders in the region, and adapt to more contemporary and asymmetric threats.

The main types of weapons in the nuclear artillery are shown. The main types of used controlled and unmanaged ballistic missiles manufactured mainly in the United States have been explored. It shows the application of ballistic and winged missiles and their role in the theater of warfare.
