If the US were to withdraw its 900 troops in Syria, what might happen?

Israel plans on doubling its population in the occupied Golan Heights, a disputed strip of land along the border with Syria. Israel captured most of the Golan Heights from Syria in the 1967 Six-Day War, and effectively annexed the territory in 1981. Israel has struck Syria more than 450 times since Assad’s regime was toppled, and Israeli forces have moved into the Syrian buffer zone which had been demilitarized as part of a 1974 ceasefire. The Israeli military says it is targeting military infrastructure. Israeli Defense Minister Israel Katz said the new rebel leaders in Damascus posed a threat to Israel, “despite the moderate image that the rebel leaders claim to represent.”
