the real question is, why would the ukraine want to join the eu? if it did, its manufacturing, which is primarily in the east, would no longer be able to produce goods for sale because of eu standards. it wouldnt even be able to sell those goods to its ichiban trading partner russia under eu law. why is it that no one was paying attention when people were protesting against loosing thier jobs by joining the eu, but after mccain goes there the people that want to join the eu all of a sudden are more important? not everyone want to move to western europe to become a maid, supermarket cashier or some other low paid hourly worker, the only jobs in western europe for eastern europeans. why would people (not brussels) in the eu, want to pay for more bailouts when they are already broke themselves after 6 years of austerity? if crimea votes to go join with russia, its people are no longer responsible for ukrainian debt. if other eastern cities decied to do the same thing, the european commission will not be able to get back any of the money it has loaned to the ukraine. that is why members of the international monetary fund arrived hours after the coup government set up in kyiv. that is why they have already started to sell of natural reasources to western countries, signing a deal with chevron to exploit shale gas in the nation.
also, russia did not invade crimea. there was already a russian military presence there and the 1997 partition treaty on the status and condition of the black sea fleet allows for a number of russian troops to move into and out of region.
you are on the internet, use it to check some of the propaganda you watch on tv for accuracy.
