The end 2008 may not be a feasible deadline for a peace deal with the Palestinians, Prime Minister Ehud Olmert on Tuesday. "In these days we are making exceptional efforts to conclude all differences with our neighbors and to resolve outstanding disputes with our Palestinian neighbors," the prime minister said in a meeting with Japanese businessmen in Tokyo. "We have a desire to reach an agreement within the year 2008," Olmert said "I am not sure we will make it, but we are determined to make a giant step forward to end this dispute once and for all." The prime minister added: "There will be no better opportunity, and we want to make every possible effort to seize this opportunity." On Monday Palestinian Authority President Mahmoud Abbas warned that if the Bush administration didn't make good on its pledge to "make 2008 the year to broker peace, then there will never be any future chances to achieve this goal."
