All this talk of Russia getting upset that "its" sphere of influence would rather look westward is completely writing off the agency of individual countries that haven't been part of the USSR for over a generation. There are very good reasons why Ukraine et al look West instead of East - chiefly riches and individual freedoms. Russia could have riches, but instead suffers from the resource curse. Russia could have liberalized, but instead continued to rely on (and is now even tightening up) uniparty-based censorship.
Say what you will about the failings and pathologies of Western liberalism. In fact, it's your patriotic duty to do so! But never take it for granted.
