If implemented as official US policy, Trump's plan could have long lasting effects on the Middle East.
Israel captured the Golan, a strategic plateau overlooking northern Israel, from Syria in the 1967 Mideast war and annexed the area in 1981. While the annexation is effectively recognized as illegal under global law, Israel has never seriously entertained giving the territory back to Syria.
Last month Guterres' Special Envoy for Syria Geir Pedersen was dismissive when asked about a push by Congress to recognize the Golan Heights as Israeli territory.
"I know that you and the president have an outstanding working relationship", Pompeo said, addressing Netanyahu.
Although Israel signalled that it would not impede the Syrian army's return to Quneitra, it has repeatedly expressed concern that Assad may defy the United Nations armistice, or let his Iranian and Lebanese Hezbollah allies deploy there.
Trump's move on Thursday was his most overt yet to help Netanyahu, who faces an April 9 election and is locked in a closely contested race at a time when he is battling corruption allegations, which he denies. "Arab leaders and Israel discussed terrorism and how to stop Iran's campaign of destruction in the region". "And the message that President Trump has given the world is that America stands by Israel".
President Trump on Thursday tweeted his support for the United States to recognize Israeli sovereignty over the Golan Heights, but like his move to recognize Jerusalem as the capital of Israel, Trump's decision is at odds with United Nations resolutions and likely won't bode well with USA critics at the world body. Mr. Trump wrote. The tweet could boost Israeli Prime Minister Binyamin Netanyahu, a strong worldwide ally of Mr. Trump's who is visiting Washington next week.
"There's no question that, at the present moment, maintaining control of the Golan Heights is of strategic and security importance to the state of Israel - particularly given the ongoing violence and instability in Syria", he added.

Shortly after entering office in January 2017, U.S. President Donald Trump visited the Western Wall, though without Israeli Prime Minister Benjamin Netanyahu.
Richard Haass, a former senior State Department official who is president of the Council on Foreign Relations, wrote on Twitter that he strongly disagreed with Trump's Golan decision.
Israel approved a controversial nation-state law past year, which says that the country is "unique to the Jewish people".
However, Leon Panetta a veteran Democrat who served as Central Intelligence Agency director and defense secretary, among other roles, blasted Trump for "tweeting out another policy that obviously has not been worked out with our worldwide partners".
Trump's foreign policy team did not respond favorably to similar requests regarding the Golan Heights previous year, expressing frustration with Israeli officials for pressuring them over a major policy change so shortly after the administration recognized Jerusalem as Israel's capital. "This recognition is long overdue, and President Trump is the first president to finally take action".
