I had ruled Syria out because of its internal problems but the point is good. Egypt is uncertain but this could also bring Hezbollah again into the picture.
Another point is the existance of the ECO and relations between Turkey and Iran. So far, Turkey has remained neutral in the disputes between Iran and Israel what if it brakes this neutrality... And, then, Brazil might come into the picture with an heavy diplomatic involvement.
Ah, I love politic-fiction...
