As The Grayzone documented at the time, the ICC charges were based on a Yale HRL report which is rife with contradictions, plot holes, and the fairly significant conflict of interest of being funded by the US State Department. The report itself acknowledges that it found “no documentation of child mistreatment,” and that nearly all of the children were returned to their families in a timely manner.
But even if these points were all false and Vladimir Putin did just illegally kidnap six thousand Ukrainian kids to turn them into Russians, would that be worse than murdering them by dropping powerful military explosives on areas known to be packed full of children? Why is one a war crime and the other apparently fine? Russia is no more a party to the ICC’s Rome Statute than Israel is, after all.
