There are no coincidences in the Middle East. Not between the Israelis and the Palestinians; not between Fatah and Hamas; and certainly not between the international community and Israel or the Palestinian Authority. What there are, this time around, are startling confluences in planning and policy that have driven a wedge in Arab unity while providing unprecedented illustrations of cooperation between Israel and some of its neighbors. Operation Cast Lead, as Israel calls it, foreshadows far more than another temporary period of relative quiet along a border. At work is a fascinating scenario in which Israel "does the deed" - toppling Hamas - which arguably benefits the Palestinians, Egyptians, Saudis and other Arab states as much as it does Israel. (Jordan faces a special dynamic.) But there's more: in doing so, is Israel in effect clearing the way for an agreement with the Palestinians (Road Map) and with the entire Arab world (Arab - nee Saudi - Initiative)? For months there has been speculation as to who will invade Gaza: could Mahmoud Abbas and his American-trained cadre of fighters do the job or must it be the Israelis who clearly wanted to avoid taking the plunge and risking the ever-present quagmire? As Egyptian Foreign Minister Ahmad Abu Al-Gheit admonished Hamas at a Cairo news conference after the Israeli campaign began, it could not fire 300 rockets into Israel between the December 19 end of the "calm agreement" and the December 27 response without forcing Israel's hand. Israeli military planners, meanwhile, never doubted the Hamas obstinacy and certain course to conflict. IT WAS a lesson about which Jerusalem and Cairo were very much in synch. Egypt went to the well twice and came up empty: in its attempt to negotiate a rapprochement among Palestinian factions; and in its attempt to negotiate an extension to the Israel-Hamas "calm agreement." With a presumed good measure of prodding from the White House and vigorous nodding from the US administration-elect, President Mubarak took the decision not to allow American largesse to crumble at the self-defeating hands of Hamas. Once he took the plunge, the Egyptian president never vacillated, showing courage in feeding Hamas the disinformation that flushed its leadership out of hiding in time for the first Israeli assault; fighting back the surge of Gazans trying to enter Egypt; and allowing Al-Gheit to cast the blame for the Israeli onslaught on Hamas itself. Courage helped-along by a fear of the Muslim Brotherhood and allure of continuing American aid. Mahmoud Abbas, meanwhile, emerges as the primary beneficiary of this extraordinary convergence of interests. Gingerly testing the waters from Riyadh and from Cairo - anywhere but Ramallah - he provided an important piece to the puzzle. When Saudi King Abdullah phoned President George W. Bush to demand that Israel be reined-in, Abbas himself was still in the city, the two leaders having just met. No coincidence here, either. To some this suggests the Saudis, Americans and Palestinians were all on the very same page as the Egyptians and Israelis, notwithstanding the rhetoric. And Iran? Not much in the way of sabre-rattling this time around. Teheran fights Israel through proxies: the Syrians; Hizbullah on Israel's northern border; and Hamas down south. Syria continues to weigh the long-term benefits of patching-up things with Washington; Hamas is being left with little but rhetoric; and some military wonks believe Nasrallah is savvy enough to realize he bit the bullet in 2006 and should not be quick to bite the apple again. Accordingly, it is noteworthy that Nasrallah inveighed against Cairo, not Jerusalem, when Operation Cast Lead began. In all, while remaining mindful that not without reason generations of peace-making in the Middle East has failed miserably and that courses chartered through the region are rarely completed, the participants appear to have put on an impressive demonstration of coordinated international gamesmanship that, in its first stage, was carried out with precision planning and cooperation that extended across ancient fault lines. Whether the planners will achieve their respective goals in subsequent stages will depend on their ability to remain focused on the benefits of their cooperation and eschew impulses to push beyond agreed limits.
