1. Wrong about?
2. Please quote me saying I support the existence of Israel.
3. I did look into it and this is what I found. Seems like the negotiation have been attempted. However part of that agreement is that the Palestinians have to agree to be peaceful and not continue to war to return which their leaders have refused to agree to.
"The issue of the Palestinian refugees was the major obstacle in the negotiations. According to Cohen, "The Arab delegates were not inclined to take
notice of Israel's declared willingness to repatriate 100,000 refugees, claiming that
so long as the refugee problem in its entirety was not solved in accordance with the [United Nations General Assembly Resolution 194], there could be no negotiations for peace.'' 92 Resolution 194 states that those refugees who wished to return to their homes and live in peace with their neighbors should be enabled to return at the earliest possible date. 193 However, the Arab delegations insisted on the return of the refugees to Israel, but refused to give any guarantees to Israel that they would discard their policy of eternal hostility and their preparations for a "second round" against Israel.
Meanwhile, the Israeli delegates expressed a willingness to discuss the refugee problem, but maintained that it could be solved only within the framework of a general peace agreement.194
Furthermore, it appeared that the Arab states used the refugee issue as a
bargaining card. Not only did the Arab delegations at the Lausanne Conference
reject Israel's declaration to take back 100,000 refugees without serious
consideration, but they also displayed anger toward the Palestinian refugees, who became a pawn in the intra-Arab political game"
