What happened to the once Great Eastern Europe?

Imagine Croatia , Serbia , Kosovo, Slovenia , Macedonia, Bosnia , and Montenegro form into the once proud nation of yugoslavia again... And if all former USSR states/countries form together to again make the superpower of the USSR . Someone needs to show America, Uk etc that Eastern European countries should not be tossed around but none of the current presidents seem to have the balls to do it" They all are seeming to lean towards the US for support and have all turned Pro-Western. These once proud nations are now looked down on and pityed. Isnt it about time that Eastern Europe and these so called"3rd World Countries" stand up to the big Western Bullys
. Who do you think would win in an all out war ( no nukes ) Yugoslavia & USSR or the Usa

I am english. I dont like eastern europeans from the ones i met, nice countries though. USA would win.

Eastern Europe, as you are referring to it was merely a cobbled together 'world' instigated by the powerful at the expense of really people and/or countries.

It will take more than a lifetime to replace what was taken away from them.

Small is beautiful (not to mention it will assist in balancing world economy)
