This analytical paper examines the systematic destruction of Ukraine's cultural heritage by the Russian Federation during the full-scale war, framing it not merely as collateral damage, but as a deliberate algorithm of aggression aimed at dismantling Ukrainian national identity. The author argues that protecting cultural assets is an integral component of supranational security. The paper advocates for a strategic transition from a reactive model of simply documenting losses to a proactive "architecture of return." To achieve this, the author proposes a comprehensive mechanism based on "legal engineering," which includes: the creation of next-generation national registers to generate legally significant evidence for future international tribunals; deep synchronization with global tracing databases (UNESCO, Interpol, Blue Shield); the institutionalized application of Asset Recovery and Management (ARO/AMO) tools by law enforcement and intelligence agencies; and the mobilization of international resources for community-led reconstruction. The study concludes that Ukraine must respond to cultural aggression with flawless legal mechanisms to ensure inevitable restitution and restoration.
