Bersidsky is making the point that there was an overwhelming desire on the part of the majority of the people of Ukraine to try for western systems;that even without the machinations of the CIA a change in favor of the west was inevitable.
Stone is however more interested in distillation; in removing the fog, especially for his western readers.
Now whether it (westernization) will succeed a la Poland is debatable. I guess Ukraine's oligarch system is a big negative.
I noticed RT has more than welcome Stone.
