Actually I think Hezbollah is being used as a patsy so Iran could deflect the worlds attention away from the nuclear program. They are simply just one of many fronts of the Iranian military. Once Hezbollah starts running out of ordinance, then Hezbollah will start negotiating, but with outrageous demands as usual. The MSM will then immediatly jump on Hezbollah's side claiming they are the ones offering an olive branch and the mean Israeli's don't want peace.
Hezbollah is a Iranian 5th column. The pawns on the chess board for the Iranians. The pawns always get sacrificed first.
Here, if Hezbollah dies an heroic martyr death then Israel becomes the focal point of the world and Iran's nukes, as you say are forgotten. But Iran does not forget and Hezbollah's death allows Iran the freedom to develop and implement their own Manhattan Project with much less interference. Good Call.
I have the sickening feeling you are right. Nonetheless, I think this is something that needs to be done.
