Russia's intervention is read mostly as a rebuke of Obama, but that's because the American public is deluded by personality politics. In truth, Russia's intervention was much more of a boon to the U.S. (and that includes Obama) than a hindrance. Russia and U.S. are competitors, but they have no choice but to cooperate when it comes to defusing arms races and national rivalries in the Middle East.
I should mention that Russia itself was in an awkward position because the use of chemical weapons in the Middle East is a special taboo because it harms all of our interests to see one of the global economy's primary sources of energy spiral into sectarian conflict, and Syria is in their camp. From a diplomatic perspective, Russia dropped the ball in allowing Assad to use chemical weapons.
