The major problem for Ukraine... one that made all subsequent ones possible... is that it never had ‘pro-Ukrainian’ government..... It’s always had Oligarchs scamming the people and making deals that cushion their own purses...and this for decades!.... Their political class is morally bankrupt and cares only for lining their own pockets....not unlike other nation leaders but these are especially greedy. They have little compassion for their own people...it’s every man for himself.
Kiev will never agree to federalization no matter how much better the country would be for doing so and will fight it every inch of the way. They would loose the control they need in order to control the revenue they covet to their own coffers.
