The ukrainian urban youth doesn't seem too happy with that though.
Ukrainian youth is jobless, broke and pretty much pissed off. Like youth in every other post soviet country. It's not hard to mobilize them for whatever cause, if you know how to do it.
Leaders of these demonstrations, revolution, whatever, are the same scum as those currently in power. They are doing this to stop being the horse and become a rider instead, for few years to come.
There is no real revolution without blood. Ukrainians already did same shit years before and it didn't work. Same happened in my country and it didn't work. If you want it properly done, some heads gotta roll.
They probably expect their country to move away from Russian influence and go towards Europe but that's not possible because of location and other factors. There are big businesses going through Ukraine, which are controlled by Russians. EU is only doing this to get some leverage in the future, not because they care about Ukrainian people.
