Below is a partial list of the rebel groups that are fighting Assad and by default Hezbollah, Iran and Russia inside Syria…

In almost any conflict, the name of the game is “size, money and momentum,” with ideology a distant fourth. For the anti-Assad fighters in Syria, this reality is no different and right now, whether the West likes it or not, the momentum is all on the side of one ideology — pure Islamism. They have become the dominant fighting forces thanks to cash, training and weapons from the Gulf states (along with Turkey and Saudi Arabia).
