Challenges to national defence in contemporary geopolitical situation

The military forces and means are used to fulfill humanitarian tasks of civil protection and to fulfill the tasks of the Police of the Czech Republic in serious situations endangering lives, health, property, or the environment. If the responsible administrative authorities, territorial self-governing bodies, fire protection authorities, or military rescue units are unable to provide rescue work or liquidate the consequences of a disaster on their own, the military is called. In addition to conventional defense tasks, it is therefore necessary to ensure the overall preparation of all components of the army for the performance of other tasks in cooperation with civilian authorities in their own territory. The paper focuses on the issues of civil-military cooperation, active advances and current capabilities of the Army of the Czech Republic in providing cooperation in rescue and liquidation work in the regions of the Czech Republic. The analysis of this issue identified the key aspects and for the subsequent determination of the evaluation criteria, the multi-criteria method was applied. The authors suggest certain procedures for updating the current situation that could be applicable in practice.

Growing maritime activity, climate driven changes, and geopolitical competition are increasing the strategic importance of the Arctic and raising new security concerns for NATO. This study examines how defence and security professionals in Lithuania perceive Arctic geopolitical risks, NATO maritime preparedness, regional threats, and future security scenarios. A quantitative survey was conducted using a five point Likert scale. Data were analysed using descriptive statistics, Spearman rank correlation, the Kruskal Wallis test, and K-Means cluster analysis. Three distinct respondent opinion clusters were identified: Manageable Situation, Lowest Perceived Threat, and Growing Threat. The results showed that stronger perceptions of geopolitical competition were associated with higher perceived escalation risk. Perceived Russian threat was positively associated with support for increased NATO investment in long term Arctic capabilities. In contrast, assessments of NATO preparedness and respondents' professional experience were not significantly associated with perceived escalation risk. The findings indicate that support for stronger NATO engagement in the Arctic is mainly shaped by perceptions of specific security threats rather than general assessments of NATO capabilities. The study supports continued attention to long term maritime capability development, regional cooperation, and changing Arctic security conditions.
