The IDF is cutting the Hezzies off in the middle. Damascus is cutoff from the Hezzies and the Hezzies in southern Leb will be cut off from their command and control. What may come next brings to mind Isaiah 17:1...
Behold, Damascus is taken away from being a city, and it shall be a ruinous heap.
Remember Damascus isn't just a city, it is thought to be the world's oldest city.
