The proposal gives Israel an effective veto on the return of Arab refugees expelled in 1948 while requiring it to restore the Golan Heights to Syria and allow the Palestinians to establish a state capital in east Jerusalem.
A bipartisan group of senior foreign policy advisers urged Obama to give the Arab plan top priority immediately after his election victory. They included Lee Hamilton, the former co-chairman of the Iraq Study Group, and Zbigniew Brzezinski, a Democrat former national security adviser. Brzezinski will give an address tomorrow at Chatham House, the international relations think tank, in London.
The advisers have told Obama he should lose no time in pursuing the policy in the first six to 12 months in office while he enjoys maximum goodwill.
Livni, the leader of Kadima, which favours the plan, is the front-runner in Israeli elections due in February. Her rival, Benjamin Netanyahu, the leader of Likud, is adamantly against withdrawing to borders that predate the Six Day war in 1967.
Ehud Olmert, the prime minister, last week expressed his support for Israel’s withdrawal from the West Bank Golan and east Jerusalem.
