Challenges to national defence in contemporary geopolitical situation

Contemporary military operations increasingly face incidents in which the nature of the hazard is initially unclear, involving possible chemical, biological, radiological, nuclear, explosive, or combined threats. In the Czech military environment, the role allocation between the Military Police and other military actors in uncertain chemical, biological, radiological, nuclear, and explosives (CBRN-E) incidents is not fully standardized. As a result, the Military Police may be expected to involve in scene control, personnel protection, preservation of evidentiary value, and escalation decisions despite limited organic CBRN capabilities. This article proposes an experimental research design for evaluating Military Police response to uncertain CBRN-E incidents under controlled but operationally realistic conditions. The model integrates tactical, technical, legal, and forensic variables and introduces a structured evaluation framework focused on decision latency, exposure risk, evidentiary integrity, coordination effectiveness, and procedural compliance. The study supports future standardization of response procedures, training, and coordination between the Military Police and specialized military units.

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 article presents the current model of readaptation measures, indicating possibilities for modification of the social readaptation system. It is proved the necessity to change the existing model of social support into model of social integration of excluded people for achieving their personal benefits and overall social security in society. Inclusive participation of society in social readaptation as well as the adequacy and individualization of the support offered, constitute an important component of the effective management of resources in the social readaptation system considering the people released from penitentiary institutions. To develop a holistic strategy of re-adaptation procedure it is required active and integrating participation of the society in assistive measures aimed at people leaving prisons and being at risk of social exclusion or requiring help and institutional as well as social support. Optimization of the model of social readaptation and reintegration is based on the involvement of local community, represented by the growing number of institutions and aid organizations in Poland. This integrative approach is a core feature of modern system of social re-adaptation. Hence the changes in this regard require a departure from the “silo-facade” model and focus on the “cooperative” model in order to achieve personal benefits from efficient reintegration and social security in the state.
