Israel will not withdraw from the entire Golan Heights in return for a peace deal with Syria, Prime Minister Benjamin Netanyahu's top policy adviser said in an interview published Friday, rejecting Syria's key demand for an agreement with Israel, AP reported. The two countries could split the territory, suggested Uzi Arad, Netanyahu's national security adviser and the aide widely seen as closest to Netanyahu. But in the comments in the daily Haaretz newspaper, he said Israel must remain on the Golan Heights to a depth of several miles and cannot withdraw in full even in return for a peace agreement. Israel captured the Golan Heights in the 1967 Mideast War and annexed the territory in 1981, a move that was never internationally recognized. Syria has always maintained that peace will be possible only if Israel withdraws entirely from the Heights.
