Why would he want to do that, when it was the Soros-supported O administration who did so much to help strengthen Russia while substantially weakening the US. Soros and Putin share the same basic world view, as of course does his puppet in the White House. Putin couldn't hope to have better allies than he does now. It was the O administration who afforded him the opportunity to move into Syria with a real chance of ultimately taking control of the oil/gas-rich strategic Middle East. This in addition to what the Russians are in the process of doing in Eastern Europe, Crimea, etc.
You’re forgetting that Russia issued an international arrest warrant for George Soros not that long ago, there’s no love lost there. They blame him for much of their economic difficulty, perhaps even the currency crisis of 1998. If Soros is some sort of Russian pawn, they’re willing to endure all manner of economic difficulties to maintain cover. Seems improbable.
