Looking at the map alone and the East and west populations differences....why not just divide Ukraine at the river....Those in Ukraine who want to be part of the EU can move across the river....and those on the Western side can be a part of Russia again.....thus EU gets part of Ukraine and Russia gets a buffer zone.?????
Ukrainians won’’t like it but at this point if they want a country left at all it might be a good solution....they’d still have a state...Zelensky and be in the EU.
