Crimea is in Ukraine, not Russia. I doubt even Yanukovich would risk his EU trade deal by anteing up with Snowden on top of Tymoshenko.
Also, without supporting the US 's actions to stop the Soviet's incursions into South America, those countries are infinitely better off than Eastern Europe. Imagine if they were at the same level of development as Romania or Bulgaria. Imagine if every archeological treasure was in Petersberg like Ukraine and Georgia.
