JERUSALEM — Acting Prime Minister Ehud Olmert presented a sweeping vision for Israel's future in interviews published Friday, saying he will dismantle most West Bank settlements, fortify remaining settlement blocs and set the nation's borders by 2010.

The blueprint presented by Olmert, the frontrunner in March 28 elections, is the most detailed proposal for Israel's borders ever presented to voters by an Israeli leader, and it represents a major electoral gamble.

But with polls showing his Kadima Party slowly losing support — though still maintaining a strong lead over its rivals — Olmert gave detailed interviews to every major Israeli newspaper about his post-election plans.

Olmert said he intended to solve Israel's main security problems and to preserve its status as a democracy with a Jewish majority, taking drastic unilateral action if need be.

The plan follows Prime Minister Ariel Sharon's unilateral pullout from the Gaza Strip last summer. Olmert became acting prime minister after Sharon suffered a devastating stroke Jan. 4.

Under Olmert's outline, Israel would uproot many of its West Bank settlements and pull back to a border that would largely follow the separation barrier it is building in the West Bank, though the route would be adjusted, he said.

He said Israel would retain control over the large settlement blocs, where the majority of the 253,000 West Bank settlers live. He would try to persuade settler leaders to agree to the border, and planned to move displaced settlers into the large blocs, he said.

Israel also would keep most of Jerusalem, including its disputed holy sites, which Palestinians claims as part of the capital of their future state. However, Olmert said he was prepared to give up some outlying Arab neighborhoods of the city.

Palestinian officials rejected Olmert's plan, insisting final borders between Israel and a Palestinian state must be determined by negotiations.

However, hopes of renewing peace talks were quashed with Hamas' victory in Jan. 25 Palestinian parliamentary elections. The Islamic militant group does not recognize Israel's right to exist, and Israel has rejected dealing with the Palestinian Authority once Hamas forms a Cabinet.

Ismail Haniyeh, the incoming Palestinian prime minister, said Friday that Hamas will need several more weeks to name his Cabinet but that the Islamic movement plans to stick to its "vision," signaling that Hamas has no plans to back down from its refusal to recognize Israel or renounce violence.

Palestinian President Mahmoud Abbas and Haniyeh met Friday and said they agreed to extend the deadline by two weeks, until the end of March.
