If Stratfor is taking that from US intelligence it is presumably from the same geniuses who regularly offer us their acute historical analysis of the Middle East in the pages of the Weekly Standard and NR - it sounds at about their level. The Soviet Union did come as close as any power did to uniting Eurasia - that is a decade plus starting after WWII to the late fifties - by that point Mao had decided he had no interest in playing second fiddle to the the Soviets and Western Europe had been consolidated into the Western Bloc under NATO. Nor does Belarus have much to do with 'breaking up' Russia - at its most cynical it can be seen as seeking to take a client state of Russia's and turn it into a client state of the US - that's no more breaking up Russia than the USSR's support of Castro was breaking up the US. The article also suffers under the bizarre delusion that the US invasion of Iraq happened last fall, so I'd be a bit wary of taking it too seriously.
