Challenges to national defence in contemporary geopolitical situation

This paper analyzes one-way attack UAV saturation and air defense adaptation using open-source attack data recorded by Shahed-136/131 UAVs in Ukraine. Descriptive statistics, correlation, regression, and non-parametric tests indicate rapid growth in UAV volume, partial saturation effects, and a clear distinction between kinetic destruction and broader neutralization. The study contributes a measurable counter-UAS assessment model that links attack volume, defensive performance, and small-state air defense planning.

The article presents a comprehensive examination of the Russian Federation’s use of United Nations (UN) mechanisms to advance its geopolitical objectives, obstruct international initiatives that contradict its policy, and wage information and psychological warfare. The analysis indicates that the Russian Federation’s participation in the UN Security Council lacks a clear legal foundation, raising questions about the legitimacy of its use of veto power’. It is documented that Russia systematically uses this privilege to veto resolutions aimed at condemning its aggression and investigating war crimes, thereby prolonging the war and evading accountability. Significant attention is given to Russia’s manipulation of UN peacekeeping operations, which it seeks to exploit to consolidate control over occupied territories. The study emphasizes Russia’s information and psychological operations within the UN, which facilitate the spread of disinformation, undermine trust in international institutions, and adversely influence state voting on critical resolutions in the General Assembly. The results obtained illustrate the necessity of revamping the UN decision-making mechanism, particularly by limiting aggressor states’ ability to exercise the veto in their own interests. Proposed procedural reforms aim to enhance the UN’s effectiveness in maintaining peace and safeguarding international security.

The human factor is a source of errors that arises not only in airports activities but also in the process of internal and external communication. The hybrid campaign consists of a spectrum of classic tools, called DIMEFIL, which affect the dimensions of power in seven areas (diplomacy / politics, information, armed forces, economics, finance, intelligence, public order and the rule of law) [1].

Security of societies has become one of urgent issues in contemporary world. Too frequently we started encountering one or another form of malicious behavior, criminal activities or terrorism. New and complex threats highlight the need for further synergies and closer cooperation at all levels. Awareness, preparedness and resilience of societies emerge as key preconditions of further secure and sustainable economic development and general well-being. A special attention in those conditions has to be paid to development of theoretically grounded approach to protection of critical infrastructure (CIP), damage or disruption of which can be immensely harmful to unprepared and therefore vulnerable institutions and society. The aim of this paper is to lay theoretical foundations for theoretically grounded approach towards research in CIP area, in order to formulate, ultimately, an approach towards action, which, employing leadership societal stakeholders would allow to enhance awareness of society actors about the threats, i.e, to develop ability to recognize, prevent, and, in case of disaster, to resist to consequences of critical infrastructure infringement. Hence, enhanced resilience of society to critical infrastructure infringement is and ultimate goal of fostering of leadership for critical infrastructure protection.

This article discusses the Ukrainian legislation on cybersecurity. The necessity of developing an efficient cybersecurity system was raised by the hybrid war conducted by Russia over the last few years, in which many critical infrastructure objects have been destroyed with serious consequences not only for the end consumers but also for the security of the state. Consequently, Ukraine has begun issuing a number of laws aiming at strengthening its cyber defense capabilities by establishing an efficient national cybersecurity system. The analysis has clearly shown that although important steps have already been taken in this direction, much still remains to be done to protect the Ukrainian critical infrastructure.
