If, like you say, Iran has a secret facility somewhere deep in the mountains where it is making nukes with HEU, and moreover if you do not KNOW where this secret facility is, then you have no way to stop Iran anyways(!) So Netanyahu's plan to bomb Iran is perfectly useless - and Israel should accept Iran as a nuclear power already. Tell you what, Iran is playing the game of nuclear ambiguity. By constantly denying a nuclear bomb program, Iran is convincing Israel that it has one running at full speed underground in the mountains. In reality, Iran will make sure it has no such facility - because an absent facility is most difficult for Israeli spooks to find. And that makes them worry more of its existence.
