Kiev Governance has been so deeply corrupt, and robbed the people for so many decades, it will take at least that long for the people to believe their nation has a chance to get above the waterline their leaders have subjected them to...if ever.
It should not have surprised any Crimea sought leaving Kiev once the New Governance was installed......or that the East would attempt to follow suit, though they simply wanted their own Parliament and self-rule. The people have been downtrodden and beat by their government and the new one only promised it would get worse...and it has as we see the deaths and destruction in the East..
I like how you badmouth Kiev as being backward and corrupt, but then whine when the Ukrainians got rid of their corrupt leader who was a puppet of Moscow.
