US Ambassador to Israel David Friedman did not rule out an Israeli move to annex parts of the occupied West Bank, land that the Palestinians seek for a state, in an interview with the New York Times published on Saturday. Israeli Prime Minister Benjamin Netanyahu said in the run-up to an April election that he plans to annex Jewish settlements in the West Bank, a move bound to trigger widespread international condemnation and complicate peace efforts. The New York Times said that Friedman had declined to say how Washington would respond to annexation, but remarked: "We really don’t have a view until we understand how much, on what terms, why does it make sense, why is it good for Israel, why is it good for the region, why does it not create more problems than it solves." "These are all things that wed want to understand, and I dont want to prejudge," Friedman said. The White House has been working on a proposal for peace between Israel and the Palestinians, dubbed by President Donald Trump as "the deal of the century", but has not disclosed any of its details. Most countries view Israeli settlements in the West Bank, territory captured in the 1967 war, as illegal. Israel disputes this, citing historical, political and religious ties as well as security needs. Friedman said that, under certain circumstances, "Israel has the right to retain some, but unlikely all, of the West Bank". It was unclear which West Bank territories Friedman meant and whether Israels retention would be part of a peace accord that includes land swaps - an idea floated in past negotiations - rather than a unilateral move such as annexation. The Trump plan had been expected to be unveiled during an economic conference in Bahrain this month. But a snap election in Israel set for Sept. 17 is likely to delay the roll-out. Responding to Friedmans interview, Palestinian chief negotiator Saeb Erekat tweeted: "Their vision is about annexation of occupied territory, a war crime under international law."
