The already extremely complex Middle East may be on the verge of becoming even more so.
At this point, the Sh’ia northern arc of Iran, Iraq, Assad and Hizbullah is in confrontation with the southern Sunni arc of Egypt, Jordan, Saudi Arabia and the Gulf States (with the partial exception of Qatar).
Adding to the confusion are the attempt on the part of Iran to outflank the Sunni arc in Yemen, and the rampaging Sunni Islamic State athwart the Sh’ia arc.
It would appear that the northern arc may be about to suffer a further rupture. Reports indicate that Assad’s forces are on their last legs and may soon disintegrate.
