The blue circles – cities under Ukrainian control but encircled/isolated.
The green circles – cities now under Russian control.
The eastern cauldron is not entirely closed, as we can see.
The larger area in blue to the east is where the clear defeat (irreversible) of the regular Ukrainian army will happen in the next days.
Already the (western) MSM propaganda shifted focus on Kiev and the heroic battle-to-be there. Like you could sweep under the rug the eastern capitulation (when it will happen). Right, if you’re a MSM shill you can, with a smirk.
