Good rundown. Does your analysis pretty much agree with the chart at post #1?

To answer your question: the graphic is pretty accurate, but fails to address the major issue of the war between Sunni vs. Shi'ite Muslims that's been going on for 1,400 years. All of the factions in this 3-way pie either support the Sunni or Shi'ite factions.

The graphic indicates that Iran may be playing both sides of the fence in this 3-way pie. I don't know if they are, but Iran can be bipolar at times.

However, 2/3 of the rebels fighting Assad's regime are Sunni (or are aligned with the Sunnis) and that includes both Mainstream and Radical Rebels.
