It is often argued that Russia fears Islamic domination no less than the West. And while Russia certainly has good reason to be concerned about jihadists, its concern has not led it to act as an ally to the West in the West's fight against the forces of global jihad. To the contrary, like Iran and Syria and their affiliated terror groups, Russia views the US as its true enemy. Like them it seeks to exploit US weaknesses to advance its own position.
Russia understands that Iran's ideological foundations make it impossible for Teheran to ever reach an accord with the US. And it exploits the situation to its benefit.
Moscow built Iran a nuclear reactor. It supplies Iran and Syria with advanced weapons systems. Russia's alliance with Iran and Syria advances its interests in two ways: It weakens the US and it ensures that Russia will not be the target of an Iranian nuclear bomb.
But most importantly, looking ahead, both the US and Israel should take a lesson from their enemies. They must acknowledge that when they are strong and victorious, their allies are strengthened throughout the world. And when they are weak and dissolute, their allies also pay the price of their irresponsibility.
