Netanyahu is also apparently unwilling to pledge to wrap up an agreement on borders during the time when there is a settlement freeze. And the US, for its part, is reportedly unwilling to commit in writing that this would be the last settlement freeze it would ask for, apparently wanting to keep open the option of another freeze if the border issue was not wrapped up during one 90-day freeze.Defense Minister Ehud Barak, meanwhile, said at a meeting to the Pensioners Union on Thursday in Tel Aviv that to move the negotiations forward it may be necessary to change the composition of the coalition and bring in Kadima. "There is a certain contradiction between the structure of the government and the chances of deepening the negotiations," he said."We [the Labor Party] joined the government so it would go in that direction, and we are going that way but still not reaching the destination. If it turns out that this government in its current configuration can't move forward in a diplomatic process, it will be necessary to weigh expanding it and creating a national unity government," he said.Former prime minister Ehud Olmert, meanwhile, took Netanyahu to task Thursday for not agreeing to a US demand to extend the settlement freeze. Speaking to foreign correspondents, he said he wouldn't have agreed to a settlement freeze in the first place, saying it was more important to focus on larger issues like final borders, the fate of Palestinian refugees and the status of Jerusalem. But he said he would not turn down a request from Israel's closest ally and endanger ties."If someone says that he agrees to 10 months of freezing and the president of the mightiest nation on earth and friendliest nation to Israel comes to you and says 'please give me two (more) months, only two months,' I mean what could happen in two months?" he said. "I would say 'president, why two? Why not three? Take three!"Olmert suggested that both Netanyahu and the Obama administration were wasting valuable time on a marginal issue. Netanyahu, meanwhile, said the Palestinian Authority Information Ministry's recent denial of the link between the Jewish people and the Western Wall, reported earlier this week in The Jerusalem Post, "calls into serious question its [the PA's] intentions of reaching a peace agreement, the foundations of which are coexistence and mutual recognition."Calling the Palestinian "study" on the matter "reprehensible and scandalous," Netanyahu said "this is not the only instance in which Palestinians are trying to distort historical facts in order to deny the deep and historic link between the Jewish People and its homeland." He called on the PA leadership to disavow and condemn the document.
