Russia deports thousands of Ukrainian children

The report […] describes a system of holding facilities that stretch from the Black Sea coast to Siberia.

“In some cases there is adoption, other cases summer camp programs where the kids were slated to return home and never did,” [a researcher] says, “and in some cases they are re-education camps.”

[…] in May 2022, when Russian President Vladimir Putin issued a new decree that made it quick and easy to adopt Ukrainian children, which was next to impossible before the war. In addition, Russian officials announced it would extend government support to Russian families who adopt Ukrainian children.

So, if I’m not mistaken, according to the article…

• Those children should not be institutionalized.
• They are also in danger from the war.
• But they were institutionalized in Ukraine, not Russia.
• And Russia is bringing them away from the war.

So, apparently, Russia should immediately return those children to the frontline, so they can either die or be evacuated somewhere else where they’ll remain institutionalized? Because evacuating orphans from a war zone and finding families for them is apparently “a war crime” (it isn’t btw, the Rome Statute doesn’t even come close to making that a war crime).
