I suggest everyone read the happenings from 1936 to 1939 in Europe. Russia will continue to push till the force a war.
They will if they cannot win by diplomacy or threats, I quite agree.
Russia IS threatened by the move by Georgia to align with the west.
Russia's power elite know perfectly well that their power right now comes from their enormous petroeum and natural gas dominance in the Eurasian sphere.
Georgia's decision to reroute energy sources via a pipeline not going through Russia is probably the primary cause of this event.
