Great point, although the myth of Midddle Eastern unity is overblown.
Iran: Not Arabic, Persian, and keeping with your theme, ripe for the plucking. Over 50% of population under age 25 and really chafing under Islamic theocracy. They want modernity NOW. Tick Tock.
Syria: yesterday reports the government sentenced a political reformist to 5 years. Pretty bold move for the reformist, in a country that used to have no dissent. Tick Tock
I don't mention Iraq; foregone conclusion. Saudi Arabia: 11% of our imports and declining. See below.
Only remaining wild card worth serious concern is Egypt. They won't stand alone after the dominos start to fall.
Libya: effectively neutered by Reagan. All others: see domino principle above. IMHO
