Pan Arabism never really took off in the Middle East. Its members from North Africa never felt they belonged to The Arab League. If the Brits and the Americans had not informed the Israelis in the 1967, the outcome of that war would have been totally different. Plus Syria was not getting along with the rest them because the compromise it had to make in the 1967 and lost its teeritory Goaln Heights(which is still under Israeli controll). Hafez Assad always thought the Pan ARAB LEAGUE let him down during that war Jordan & Egypt's resuming diplomatic relation with Israel made it even worse. During this whole time Iran always stayed away from all this scuffle. Cause they were fighting a decade long war with Iraq. While Jordan, Saudi Arabia and the rest of the Sunni countries lined up behind Iraq and Saddam Hussain. I don't think the Iranians ever forgave them for that. BUt the final blow came when Iraq invaded Kuwait. Thats when shit hit the fans. From then on they've sort of become very hostile to each other. If you look at the current picture of Middle east the tables have totally turned. And major power player there like Saudi Arabia, UAE including Israel is getting nervous(esp knowing the fact that they are working of Nuclear capbilities). The other day the PM of Isreal had lil tongues slip about their own Nuclear capabilities, saying they might have to let their nuclear geenie out of the bottle too if Iran declares their own Nuclear capability.
