Israel must assume the worst - that real sanctions will not be imposed on Iran. The United States has two other options: actively encouraging the toppling of the regime of the Ayatollahs by the Iranian people or independent military action. As far as the first option is concerned, the U.S. is interested but has forgotten how to do it; the latter option it can carry out, but it does not wish to do so for political reasons. In the event no one stops Iran on its way to the bomb, a military option for Israel must still "be kept on the table." This, of course, while remaining aware of all the reservations and shortcomings relevant to such an option, and by viewing it as "the final option" in which only a nuclear Iran is worse. In the absence of such an option there is little chance that other countries will take action. Even if they attempt to pressure Iran economically and politically, it will have no reason to give in if it knows that nothing bad will happen to it. No one will treat Israel with the necessary seriousness if it makes do only with complaining about the Iranian threat, without showing determination to do something about it independently.
