So Obama is hip deep in trying to overthrow another Secular Arab dictator to install the Muslim Brotherhood and other Islamists in power. Soon, I expect, we will find that there are American military advisers on the ground in Syria, as well. Tunisia, Libya, Egypt, Yemen, Syria with loose weapons awash all over the region courtesy of the US war against Libya. The Greater Caliphate marches on.
Religiously it is Sunni, Shia, Ismaili, Alawite, Greek Orthodox (Antiochian), Melkite Greek Catholic, Syriac Orthodox Church, Armenian Apostolic Church and some Protestants. Then there are still some Jews, some Yezidi, some Sabateans, some Zoroastrians.
Assad may be bad, but the alternative will be worse for non-Sunnis and for Israel.
