A drive up from Metula to the river cuts Southern Lebanon off from Syria, and puts the HEZ in an untenable position where they either run, or die in place without support.
Syra CANNOT stand against the Israeli Army or Air Force, which means a War of The Missles....
This is a credible threat the Syrians do have. Their missiles (medium and long range) can target anywhere in Israel and have some guidance capability and some of the warheads are likely wmd equipped
perhaps..
But a WMD attack on Israel means the Walls of Jericho come tumbling down....
Not the desired result for a socialist dictatorship. I'm SURE they aren't as willing as President nutcase to meet thier 12 Virgins yet....
