The Impact of the War on the Economic and Legal Environment of the Regions in terms of Ensuring National Security

The main objective of the article was to study the impact of the war on the economic and legal environment of the Ukrainian regions in terms of ensuring national security. The research methodology involves the use of modern methods of graphical modeling. The scope of study was the system of economic and legal relations that emerged in the course of hostilities. With the outbreak of hostilities, there are certain legal consequences for the belligerents: diplomatic and consular relations are terminated; economic, commercial, monetary and other business and agreements with legal and natural persons of Russia are terminated and prohibited, as a special regime can be applied to citizens of a hostile state; the declaration of a state of war leads to a change in the legal regime of the territories. However, most armed conflicts are not accompanied by a legal declaration of a state of war, which, nevertheless, introduces significant changes in the legal relations of the parties. Accordingly, the key aspects of the impact of war on the economic and legal environment in terms of security guarantees were characterized.
