Did McCain Start the Russia-Georgia War?

According to the Washington Post, John McCain's principal foreign affairs adviser, Randy Scheuneman, is a lobbyist for the country of Georgia. On the one hand, McCain is well briefed on Georgia, on the other, has he been too hawkish in encouraging Georgia to tweak Russia's nose? Thanks to his lobbyist/adviser, he has talked to the Saakashvili numerous times, but what has he told him? The neocon Republicans hate Russia and want to bring it down. Did they see Georgia as a tool in their attempt to destroy Russia? Will Georgia be destroyed as a result? Is John McCain the leader of the use-Georgia-to-destroy-Russia bloc of neocon Republicans?
