"Why don't you blame the Georgians, Ukrainians, etc for their roles?"
To be perfectly honest, don't know much of about their history. However, as history has shown, post WWII, those in control were puppets of Moscow. And people that stay in control in a tyrannical environment of a few decades, get use to the privileges of being in control, and do not want to turn loose.
Bush was being a good guest. Probably hoping to get future support (i.e. abstaining UN votes) if we decide to directly confront Iran or North Korea. Hopefully it works. You can't win chess only with Pawns.
You do understand that Moscow was run, that is the Soviet Union, by a two georgians and a Ukrainian, right? This is not to say that Russians, like Molotov were not involved, but overall, Russians were a minority in the Communist party leadership upto Gorbichov. Felix, father of the Red Terror was a Pole. Lenin was half German (Volga) and his personal bodyguards were the Latvian Rifles. The father of the Gulags was Jewish (and ended up in one himself) and the father of the Gulag transportation system was equally Jewish (note: nationality not religion, all involved were atheists). Go read the linked interview with Putin. There are 4,000+ tv and radio stations in Russia, of which the government owns 1 directly and is a minority owner in 2 others.
