As I wrote in a post some hours ago my inerpretation of IDF's strategy (and I'm not an expert, at least no more than other armchair generals...) is that this time they are not going for land or other geographical objectives, this time they are going for bodies.
One advantage is that much of the fighting then will take place close to the Israeli border and consequently there will be less political pressure on Israel to accept a cease-fire.
The other advantage is that it seems like Hezbollah has amassed a lot of their best fighters in those fortified towns and villages close to the border. The advantage for Hezbollah is that they will be able to fight from prepared positions. The disadvantage is that they give up one of the large advantages of guerilla fighters - mobility.
If the IDF has decided, as I guess they have, to take this operation step by step then there is nothing for the terrorists to do but to fight and die or surrender.
Of course once upon a while they may be lucky - as they were in Jenin - but it appears that Nassrallah has sacrificd his front line troups - the "Ktyusha brigade" (I think that was an Israeli nick-name of those terrorists stationed in the villages close to the border.)
I guess the political disagreement will start once there will be requests from the IDF to continue their operation towards the Bekaa valley.
i agree this is the approach Israel appears to be taking, i just think its only a half measure. The Bekka is Hizbullah's "Eagles Nest", its the Hizbullah heartland. Tearing thru the Bekka would not only serve to deliver a crippling blow to Hizbullah it would also cut off its main source and route of resupply - Iran and Syria respectively
