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.
Wrong. The whole point is to neutralize Hezbullah (and Hamas) because they have been used by Iran to distract from their nuclear program. Once they are put down like the rabid dogs that they are, then extreme focus will be on Iran.
There have been some reports that Iran has had trouble with its centrifuges. They are trying to buy more time. They don't have much time left. Note they have not only not responded to the EU's proposition, they have sent their negotiating team to Syria to help the Hezbullah with its tactics. Their job will be finished soon and back to Iran they will go.
