Washington ? President Bush won Israel’s acceptance of a blueprint for peacemaking with the Palestinians Friday, rejecting Prime Minister Ariel Sharon’s appeal to revise the plan but assuring him that concerns about terror attacks would be addressed.

Secretary of State Colin Powell and Condoleezza Rice, the president’s assistant for national security, agreed with Sharon in a statement that the concerns were both real and significant.

“The United States … will address them fully and seriously in the implementation of the road map,” they said.

As a result of the promise, backed by Bush, to deal with the concerns while Israel and the Palestinians begin to carry out the U.S.-backed seven-page road map, Sharon will submit the plan to end 32 months of fighting and to set up a Palestinian state to the Israeli Cabinet on Sunday.

The blueprint was accepted by Palestinian Prime Minister Mahmoud Abbas last week, and the Bush administration is bracing for the violence that customarily follows from peacemaking attempts.

In Paris, where he was holding talks with other foreign ministers, Powell said, “We are looking for and believe we will receive from Prime Minister Abbas, 100 percent intent and 100 percent effort to bring terror and violence under control.”

Sharon mostly is worried whether the Palestinians can and will improve security arrangements and also about the extent of Abbas’ reform efforts. The Palestinians, for their part, are uncertain about Israel’s commitment to a viable Palestinian state being established by 2005, as Bush envisions.

The president, at a news conference at his Texas ranch, said he was “exploring the opportunities of whether or not I should meet with Prime Minister Abu Mazen (Abbas) as well as Prime Minister Sharon.”

“If a meeting advances progress toward two states living side by side in peace, I will strongly consider such a meeting,” he said.

Bush said Sharon’s acceptance of the road map was progress. “He accepted it because I assured him that the United States is committed to Israel’s security,” the president said.

On the Palestinian side, Information Minister Nabil Amr called the Israeli acceptance “a positive step.” But, at the same time, he said, “We still insist on the American and European promises and guarantees not to have any changes in the road map.”
