we consider central Europe= Luxembourg, Germany, Netherlands, center of center= Switzerland :p Estonia is far eastern block, etc.
There is eastern block skepticism, about EU generally (western block is none sense, we have no strong judgment/influence on the EU central bank, Germany, Netherlands and do on have). I think what you heard was the west, since the rest of Europe is west of them :p the rest of Europe is east of me.
But there is alot of pro-EU in power, and it's the most reasonable people since they rather fear for what's going to happen after installing the missiles than optimism of installing USA missiles to protect them. Russia already threatened to aim missiles towards EU if this happens, I don't want to become an European Israel sanctioned/hated by other countries and puppet of USA.
No other reason would lead most of the eastern European governments to try to join EU. Their markets are parallel to USA, they had alot of boom, but their economy is fragile, and becoming more and more fragile with the USA tension anywhere about oil exploitation. Here in the western area we tend to get as far as we can from USA's markets, independent all the way, so we cannot rely in the American Oil.
