Denys Kostev was 18, living in a Kherson orphanage, and posting anti-invasion videos on social media when Russian forces rolled into the city in early 2022. Within months he was in Crimea, wrapped in a Russian flag on camera, declaring his desire to enlist. The transformation was not voluntary. It was infrastructure. Kostev's trajectory maps the pipeline Ukraine and international rights groups have documented: children removed from occupied orphanages, relocated to camps in annexed Crimea, subjected to daily anthem ceremonies, Russian-curriculum schooling, and isolation from any countervailing narrative. The Luchisty summer camp where Kostev landed ran a closed compound — no departures allowed — overseen in part by a former Ukrainian special forces officer who had switched sides. Those caught breaking rules faced isolation and threats of prison. The numbers frame the scale. Ukraine claims nearly 20,000 minors have been transferred to Russia during the war. More than 4,000 were taken specifically from orphanages in occupied regions. Some 5,500 young Ukrainians in occupied areas were enrolled in Yunarmiya, a military training movement. At least 2,600 children have been returned so far, meaning the vast majority remain inside the system. Kostev's coerced propaganda appearances illustrate the mechanism at the individual level. After complaining about squalid dormitory conditions in a viral video, Russia-installed police strip-searched him, accused him of spying for Kyiv, and forced him to record pro-Russian content. One video showed him joining a Kremlin-funded youth movement. He told Al Jazeera every appearance was performed under threat of physical assault or imprisonment. The theatrical training from his orphanage days became a survival tool. Psychologists and rights groups describe the programme as deliberate identity engineering. Svitlana Chunikhina of the Association of Political Psychologists of Ukraine notes that children's flexible psyches and involuntary trust in adults make them especially vulnerable. The Norwegian Helsinki Committee's Ivar Dale calls the campaign "something more sinister" than physical destruction — a systematic effort to reprogram national identity, with some children funnelled toward military service against their own country. Kostev ultimately escaped through family connections in Germany, crossed into Poland, waited months for a new Ukrainian passport, and returned to Ukraine in April 2025. He is now training as a drone pilot. His story is one data point in an ongoing extraction operation — children as raw material, ideology as the processing plant, and a militarised identity as the finished product. The International Criminal Court issued arrest warrants for Vladimir Putin and Russia's children's rights commissioner Maria Lvova-Belova in March 2023 over the forced transfer of children. Russia rejects the charges, claiming children were "rescued from war zones." The gap between 20,000 claimed transfers and 2,600 returns defines the scale of what remains unresolved.
