This Week VN:N tw A, were again suspended in January, when Syria demanded that Israel state in writing that it is willing to with- draw from the Golan. With the help of U.S. diplomats, there have been subsequent informal contacts. Washington is said to be press- ing for agreement on the most substan- tive issues before a formal resumption of the negotiations to ensure that the process does not run aground again. If this can be achieved, the two sides could sign a peace treaty this spring. Israeli officials maintain that , this is a real possibility. Barak's dramatic raising of the stakes across the poker table this week, while welcomed in Washington, drew much stinging criticism inside Israel, and not only from the opposition. Israel's largest newspapers faulted the prime minister for trying to draw his prede- cessors into his negotiating gambit. Barak maintained during Sunday's cabinet session that former Likud Premier Yitzhak Shamir had implicitly agreed to a total Golan withdrawal back in 1991, when he consented to attend the Madrid Peace Conference on the basis of an invitation that referred to the U.N. Security Council's land-for-peace Resolution 242. Rabin, said Barak, told Christopher that Israel was ready in principle to pull back to the June 4, 1967 line if all the other elements of the peace package fell into place. Shimon Peres, Barak went on, endorsed Rabin's position. And Benjamin Netanyahu, Barak's immediate predecessor, conveyed to the Syrians his willingness to withdraw to the prewar line in a secret dialogue con- ducted by U.S. businessman Ronald Lauder, who now serves as chairman of the Conference of Presidents of Major American Jewish Organizations. Shamir and Netanyahu flatly denied Barak's version of history. "I was always against any withdraw- al on any front," said Shamir. Netanyahu, reacting from New York, said his secret negotiations failed precisely because he was not prepared to commit to total withdrawal. Leah Rabin, speaking for her slain husband, was equivocal, and Shimon Peres said he "focused on economic issues rather than on the border line." The political wisdom of Barak's histo- riography would be merely academic were it not for his need to win the Israeli public's support in the referendum that he has promised to hold when and if a peace treaty is concluded with Syria. At present, according to the polls, that sup- port is by no means assured. El
