Sounds like the IDF now has a game-plan in place.
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.
