In short, the Russian victory over Georgia means a severe blow to the United States, whose strategic position in the Caucasus region has become seriously weakened.
Former Soviet republics have also seen that the United States can do nothing to support them if they try to challenge increasingly strong Russian power. The result will be an expansion of Russian influence in the Caucasus and Central Asia and the reassertion of Russia as a world superpower.
If Russia decides to bring Georgia back into the Russian federation, then Russia will consolidate its access into the Middle East and its ability to logistically support Iran against the US and Israel.
If the Neocon planners thought that they were going to be able to use a Georgian civil war to hamstring Russia they bungled badly.
