The best thing that could happen from this latest exchange is for Israel to take Syria at their word, and declare all out war on them and their partner Iran.
After the fighting is over with Israel of course victorious, claim territory according to the rights of victory. Draw a line through Allepo east to the border with iraq and claim everything south of the line.
Carve out 60% of the territory of the former Iran and have Saudi Arabia governed for Israel. Inform Syria and Iran they have 90 days to resettle any non-Christian, non-jew in the new portion of Israel.
If any bad actors start working in Iraq, then Israel should connect their territory betwixt.
There will never be peace in the region until the borders of Israel span from the Tigres to the Nile.
Israel never should have given back the territory that Egypt and others rightly lost during previous wars.
Neither should we, but both examples are subject matter for alternate history books not yet written.
