■ Chemistry of Sharon and Peres, old friends and rivals, will be key to government longevity. DAVID LANDAU Jewish Telegraphic Agency A Jerusalem riel Sharon's national unity government, which was sworn in Wednesday, vvill rely on two key fac- tors for stability and longevity. One is a close and harmonious rela- tionship between Likud Prime Minister Sharon and Foreign Minister Shimon Peres, the senior Labor Party minister in the cabinet. The other is the continued absence of realistic prospects for negotiations with the Palestinians toward a final peace agreement. Less tangibly, the unity government will need a great deal of luck, that unpredictable commodity that outgo- ing Prime Minister Ehud Barak so lacked during his stormy 21 months in office. To say that Sharon, 73, and Peres, 77, have a long history together is an 22 Cabinet Within Interim Accords Sharon's unity government, with almost 30 ministers and another half- dozen deputy ministers, will be unwieldy at best, unworkable at worst. The Labor component, moreover, is beset by internal conflict. Several of the defeated and dispirited party's leaders — Yossi Beilin, Avraham Burg and Shlomo Ben-Ami — oppose unity under Sharon and have opted to stay out of the cabinet. As the party's lead- ership battle unfolds in the coming months, the ideological and personal fissures between pro- and anti-unity groups likely will widen. For both of those reasons, the per- ception of Peres' role will be critical. Any sense in Labor that Peres is being sidestepped or marginalized will -exacerbate internal party tensions and strengthen the hands of those calling for Labor to leave the alliance. Most analysts sug- _ gest that the govern- ment's survival will best be served by Sharon's sustaining the understanding that he and Peres together comprise an informal inner cabi- net where key deci- sions are thrashed our. That was the recipe for the success of the unity govern- ments that ruled Israel from 1984 to 1990 under prime ministers Peres and Yitzhak Shamir. In those cabinets, an inner "prime min- isters' club" made up of Peres, Shamir and The same logic may govern Israel's present political constellation. Under Barak, Labor lost the election chiefly because of the collapse of peace negotiations with Palestinian Authority President Yasser Arafat and the eruption of Palestinian violence. The alliance-of-convenience with the Likud is predicated, in effect, on the impossibility of reviving those talks. Laborites roundly blame Arafat for that; many have come to believe that as long as he is power there will be no further thrust toward peace. In practical terms, that means Israel's two major parties can work side by side to reduce the current level of violence and to aspire to limited or interim accords with the Palestinian Authority. In any case, Sharon believes interim accords over a long period are the best approach. Labor believes they are a poor substitute for full-fledged peace talks, but acknowledges that the ideal is not feasible at this time. If that reality changes, it's difficult to see how the Likud-Labor coalition could survive. The pressures inside Labor would become too powerful- for Peres to stay put, even if he wanted to, which he probably would not. Presumably, Beilin and friends will try, through unofficial channels, to revive the negotiating option with the Palestinian leadership. Meanwhile, Peres and the Labor defense minister, Benjamin Ben- Eliezer, will seek to ensure that the "no peace" situation also remains one of no war, trying to steer Sharon clear of the more militarist strains in his own personality and past, and in his pres- ent political camp. For instance, one Sharon ally — Rehavarn Ze'evi of the National Union Party, who will be Sharon's tourism minister — urged this week meats understatement. Both have been there since the creation of the State of Israel 53 years ago. The young Peres was an aide to founding father and first Prime Minister David Ben-Gurion and quickly rose in the 1950s to become director general of the Defense Ministry. There, Peres — the stan- dard-bearer of today's peace camp was intimately involved in developing Israel's nuclear potential. Sharon, a dashing infantry officer, served in Israel's 1948 War of Independence. In the 1950s, he gained fame and notoriety as the founder of Unit 101, an elite com- mando crew that carried out aggressive and controversial anti-terror reprisal raids across the Jordanian border dur- ing the precarious first decade of the state's existence. In those days, Menachem Begin's Herut Parry — which later became the core of the center-right Likud bloc — . was a powerless opposition. Politics Terror And Tears 3/9 2001 were dominated by Ben-Gurion's Mapai Parry, forerunner of today's Labor. Rising stars like Peres and Sharon nat- urally saw themselves as proteges of the "Old Man," as Ben-Gurion was called. Yitzhak Rabin took the main deci- sions, far from the debating-club atmosphere of the full cabinet. That inner sanctum never leaked. Though political rivals, its members set aside their differences in the shared interest of conducting the nation's business and preserving the viabilin- of their awkward coalition. Ultimately, the longevity of the 1980s coalitions rested on an absence of progress in the peace process. A near-fatal crisis erupted when Peres, behind Shamir's back, tried in 1987 to negotiate an agreement with King Hussein of Jordan.
