Any ‘autonomous’ zones will likely be ruled from Moscow
Well after the relentless bombing and shelling of the East by Kiev you couldn't hardly blame "the Eastern people" for hating Kiev...and they do...and being more comfortable with Russia...the lessor of the two evils....
I suspect those who don't want to return to Ukraine under Kiev will remain in Russia. Those who've vacated the East to other areas in Ukraine for safety will likely return...along with some from the West since Kiev's promising free housing for those in the West to move there....
Bottom line...Ukraine will always be in rebellion in one form or another...it's it's nature to do so.....Besides Winter's coming for Ukrainians and they all know it!
