Golan was part of the sovereign state of Syria.
Israel laid no claim to it... during the 1967 war Israel occupies it. That’s the status. It is occupied Syrian territory. Dejure Syrian, defacto Israeli occupied. No other country recognizes the Golan as Israeli territory.
There may be hundreds of good reasons why Israel won’t give back the Golan. But the Syrian President sould be the least person you’d expect simply to forfeit his country’s claim.
Did you read what I wrote? Golan is now part of the sovereign state of Israel. De jure and de facto. If Syria wants it then they are welcome to try and conquer it.
I think Trump will recognize the Golan as Israel. He will also move our embassy to Jerusalem.
