The most obvious measures might include a corridor for legitimate refugees from Syria via the Golan. Israel could then offer to set up its own camps to care for the refugees, or put these under UN auspices, or appeal to Turkey for cooperation.
Absurd as this sounds, consider the surprise of Israel’s adversaries and the prospective outcomes: Turkey’s rhetoric and inaction/rejection of the Israeli offer would expose Ankara’s hypocrisy and weaken its regional ambitions.
Quiet acceptance of an Israeli offer would hasten Assad’s demise, and establish Turkey as a true power broker between East and West.
As for Assad himself, the Syrian army is far too distracted, stretched and racked with strained loyalties to challenge Israel on the Golan. If nothing else, Israel could restore the respect and quiet loyalty of the Druse.
If a handful of the refugees are of Palestinian descent, so be it.
