Kinda strange if you think about it superficially... stick with me. Iranians don't need Nuclear power. Perhaps they do want "the bomb." But, they know from past experience (with regard to Iraq) that the Israeli's will respond to that given threat. Indeed they must. And so, Iran, announcing its intentions, invites the inevitable response. Why?
Osama failed! He did not create the expected uprising of the Islamic front. Do the Mullahs of Iran believe that they can instigate a provocation by inviting attack?
Regardless, Israel must act, with expedient demise.
