It could have been dictated by Moscow's troll factories. Give Putin this time what he will be content with to avoid nuclear war.
1. If Putin is insane, then nuclear war is inevitable anyway.
2. If He isn't insane, giving him anything now guarantees he will regroup and be back for more. Followed, at some point when it goes too far by WW3,
logically, therefore, only defeat for the rapists and other war criminals (preferably with a Nuremberg style trial and sentencing of the criminals, but I don't hold my breath on that one) is the only possibility to avoid WW3. QED.
