Per the https://understandingwar.org/backgrounder/putin-still-stealing-ukrainian-children link
"The adoption process strips Ukrainian children of their Ukrainian names and birthplaces, replacing them with Russian birth certificates and documentation intended to erase the childs Ukrainian identity and any paper trail that would allow Ukrainian authorities or family members to search for the child. For teenage Ukrainian boys, their forced acceptance of Russian citizenship can result in a near immediate military summons to fight in the Russian army against their fellow Ukrainiansa completely separate but equally clear violation of international law. The Russian adoption system is swallowing Ukrainian children up into a bureaucratic black hole, premised on the administrative eradication of Ukrainian identity. For the younger children, especially those adopted in their infancy, their adoption means that an entire generation of Ukrainians are growing up in Russia, unaware that they are Ukrainian."
