The Ukrainian nation since the 1916 revolution have wanted one simple thing, which they had for a short period between 1917 and 1919 to be an independent country who decide their own destiny.
It is unlikely, Russia will directly intervene where they have a powerful economic lever they can pull on to keep the pro-Russian president inline, the only way that would change would be if a Ukrainian government attempted to closed their Black Sea base which is very likely where the current Government negotiated a new long term agreement with them recently. All countries will do what they need to do to preserve their military strategic interests.
West Ukraine was part of the Polish empire for many years and what the people in west-Ukraine want is a modern state in Western Europe. They have had enough of the corrupt post-Soviet state and a very slow reform rate and want a generation of politicians who will achieve that. What the people of post-Soviet countries want most of all is economic and political freedom, with a few exceptions of the older generation who preferred the regimented order of the old system. They have lived under the total failure and straight jacket of a feudal communist system of great privilege for the few and abject poverty with no freedom of expression for the many and have seen what liberal capitalism has done to lift their countries since 1991 so the average person is much wealthier and comfortable than before, by being able to buy the necessities and the odd luxury, which were not available under communism, but also a much more important freedom, freedom of expression. By looking west they can see that much more needs to be done, to rid the country of the last vestiges of the old corrupt communist system and to become a much more modern richer state in freedom and wealth for the average citizen.
They recognise the country is at a crossroads and know which road they want to take, so I hope it works out for them.
The removal of statues of Lenin has been happening all over the Ukraine since 1991. When I first started visiting Talne in the Ukraine, I got my future wife to take some pictures of me underneath Lenin's statue in their central square, that is no longer possible as the statue has been removed. Why preserve statues of the architect of a failed and discredited system when you are trying to write the next chapter in your country's history?
