Challenges to national defence in contemporary geopolitical situation

This article highlights the issue of national security through the lens of literature development. Since the information war has been going on against Ukraine for a long time, the instruments of influence on the consciousness of the population are constantly changing and the forms and methods of information dissemination are being improved, we decided to investigate the literary sources created during the Anti-terrorist Operation / Joint Forces Operation (further - ATO/JFO) period in order to highlight the trends of opinion formation. We used content analysis methods as a basis. The analyzed source base confirmed the thesis that fake and post-truth are artificially created and manipulative-imitation technologies that Putinists use for hybrid warfare. By imposing the post-truth era on the international community, the Kremlin regime creates a reality where emotions are dominated by facts. Thus, Russia's information strategy is based solely on the needs of the lower order.
