Earlier, the FSA has warned that it will carry the fight into the Shi'ite areas of Lebanon.

As I have posted repeatedly, if you look at what is happening in Lebanon, Syria, and Iraq, you can clearly see evidence of a deepening sectarian struggle between Sunni and Shi'a Arabs. The Iranians, I would argue, are now "all-in" with Assad, and the Russians are clearly increasing their support. On the other side, supporting the FSA, are the Turks, most of the Arab states in the Arabian peninsula, the Muslim Brotherhood, and assorted Sunni Jihadists. The EU is leaning ever more toward FSA support.

What is US policy? Obama is still working on that.
