Second, do you really think that the solution that was given in the Balkans is good? Even today, many people are deeply unhappy about it.
Only if you never bothered to ask the center- and left-inclined population of each country (which was quite substantial) -- and ignored the protests against them.
And with the help of a few interventions (e.g. in Italy) and dictatorships (e.g. in Greece) imposed when needed to keep some pro-US goons in government.
Just how much of the European "protest culture" of the 1970s and 1980s actually grew organically, without covert Soviet backing?
A, yes, it was the Russians all along, which, retroactively also proves that they control the world now from some building in St. Petersburg. And when they get some friendly lackey in power like Yeltsin again and be buddies and everything, there will be another enemy du jour, arabs (just not the Saudis) are good for that.
It's not like there ever was a very strong European left movement (or an American one for that matter), or that people in different countries in Europe have devoted their lives, risked careers, gone to prison, even tortured or executed for being pro-communist (or perhaps they did all that because they were paid)...
