Maybe the IDF is still having trouble with deeply entrenched positions is S. Lebanon. But by threatening the heartland (Bekka), they force the Hizzies to redeploy. To redeploy they have to move. If they move, they die. If they don't redeploy, the IDF goes after Bekka again.
I must say, I'm a little disappointed this was just a hit and run. I would prefer search and destroy in Bekka. But if the map is any indicator, the IDF force would be pretty vulnerable to a Syrian counter attack there and the supply lines would be all by air.
Cutting their lines of supply and flanking them out of their fixed positions.
All day the Hezbos were saying that they had the Israeli commandos surrounded. Hey Hezbos how did that work out for you?
Personally, I was hoping the Israelis had dropped a blocking force in and were going to drive the Hezbollah scum up the valley and trap them. Oh, well.
