" As far as I know, the Golan Heights was annexed by Israel, all nice and legal."
I would suggest you do not know very much then.
Annexation is the administrative action and concept in international law relating to the forcible transition of one state's territory by another state. It is generally held to be an illegal act.

(27 Apr 2016)"The UN Security Council has rejected Israeli Prime Minister Benjamin Netanyahu's claim that the annexed Golan Heights in Syria would "for ever" remain under Israeli control.The 15-member council agreed on Tuesday that the status of the Golan, which Israel seized from Syria in 1967, "remains unchanged", Chinese Ambassador Liu Jieyi, who holds this month's council presidency said. Liu recalled a 1981 resolution which states that Israel's "decision to impose its laws, jurisdiction and administration in the occupied Syrian Golan Heights was nul and void and without any international legal effect."
