Well..if those are the bare naked choices, then we should be fighting for Russia now and not a bunch of Islamist savages.
Russia is the entity that, at present, is advocating for stability, as in no change in recognized legal governments in the Middle East for the reasons I stated.
Considering the degradation of peace, security, human rights and human liberty in all the ME nations that have recently "reformed" their "democracies" (Algeria, Egypt, Libya), the Russian policy of "no change of the legal, recognized government" is the best course of action for Western Civilization and the most detrimental to the rise of the World Caliphate.
Obama and the American DemoRats would only fight for Russia when they were the Communist Soviet Union, not now.
