Communists and radical islamists are, by far, our two main foes. If they ever do succeed in defeating us, as an alliance, they'll then go after each other. The backward, primitive radical islamists won't stand a chance against the far more sophisticated capabilities of China, Russia, Venezuela, North Korea and others.
This may well be a warning to the Islamic terrorists not to mess with Russia—or it may have a plan of some sort. If its true it might be a new attempt of Russia to become our new friends and customers for their oil.
