Wouldn't Iran using nuks be suicide?

Anyone who thinks that Iran will not use nuks against Israel once they get them (infinitely easier now with the Obama/Kerry appeasement deal,) you must read what one of the world's greatest Islamic scholar and the Ayatollahs themselves say about it. "Strike Iran now to avert disaster later.” Podhoretz recalls:
As Bernard Lewis, the leading contemporary authority on Islam, put it , to these fanatics “mutual assured destruction is not a deterrent, it is an inducement. We know already [from the Iran-Iraq war] that they do not give a damn about killing their own people in great numbers. . . . They are giving them a quick free pass to heaven and all its delights.”
Nor were the rulers of Iran deterred by the fear that their country would be destroyed in a nuclear war. In the words of the Ayatollah Khomeini, who brought the Islamist revolution to Iran in 1979: “We do not worship Iran, we worship Allah. . . . I say let this land [Iran] go up in smoke, provided Islam emerges triumphant in the rest of the world.” (The quote appeared in a 1981 Iranian collection of the ayatollah’s speeches. In later editions, that line and others were deleted as Iran tried to stir up nationalistic fervor amid the war with Iraq.)
And here, speaking in particular of a nuclear exchange with Israel—that “cancer” which the mullahs were and are solemnly pledged to wipe off the map—is the famous “moderate” Hashemi Rafsanjani, in an Al-Quds Day sermon at Tehran University on Dec. 14, 2001: “Application of an atomic bomb would not leave anything in Israel, but the same thing would just produce damages in the Muslim world.” Mr. Rafsanjani, an earlier president of Iran, is the sponsor and mentor of its current president, that other celebrated “moderate,” Hasan Rouhani.
