Israeli Prime Minister Ehud Olmert is in a bit of hot water, or should we say, more hot water. In an interview with a German TV station, broadcast on Monday, Mr. Olmert inadvertently listed his country among the world’s nuclear powers, violating the long-standing policy of not officially acknowleding that it has nuclear weapons.
Asked by the  interviewer about Iran’s calls for the destruction of Israel, Olmert  replied that Israel has never threatened to annihilate anyone.
“Iran  openly, explicitly and publicly threatens to wipe Israel off the map,”  Olmert said. “Can you say that this is the same level, when you are  aspiring to have nuclear weapons, as America, France, Israel, Russia?” 
Israel,  which foreign experts say has the sixth-largest nuclear arsenal in the  world, has stuck to a policy of ambiguity on nuclear weapons for  decades, refusing to confirm or deny whether it has them.
Olmert’s  comments touched off a firestorm of controversy in Israel, where  political opponents called for him to resign (not a bad idea, but it  should be for other reasons, namely his mishandling of last summer’s war  with Hizballah).  In response, Olmert’s aides said that the Prime  Minister’s remarks had been “misinterpreted.”  They claim that he was  including Israel in a list of “responsible” nations, not nuclear powers.   
Whatever.  
Fact  is, Israel is a nuclear power, and has been for decades.  Indeed,  Israel’s membership in the nuclear club is among the world’s worst-kept  secrets.  By some estimates, the Israelis may have as many as 200  nuclear weapons, ranging from gravity bombs (carried on tactical  aircraft), to missile warheads, which can be mounted on their Jericho II  medium-range missiles.  The Israeli nuclear program has always been  shrouded in secrecy, and various governments have spared no effort to  punish or discredit those who “betrayed” the nation’s nuclear secrets.   In the mid-1980s, a fired nuclear technician, Mordecai Vanunu, provided  information on the nation’s weapons program, including photographs of  nuclear warheads, published in the Sunday Times of London.  For his efforts, Vanunu served an 18-year prison sentence.
The Federal of American Scientists has  an interesting, if a bit dated, summary of the Israeli nuclear program,  including the estimated size of Tel Aviv’s arsenal.  You’ll note that  two decades after Vanunu’s disclosures, we’re still guessing about the  number of weapons that Israel actually has.  
Being  deliberately vague on the nuclear issue has worked to Israel’s  advantage.  Potential foes have often over-estimated the size and reach  of the Israeli arsenal, increasing its deterrent value.  And, surrounded  by enemies for much of its existence, Israel can make the case that it  needs nuclear weapons to defend itself.  On the down side, the Israeli  program helped trigger the long struggle for an Islamic bomb, which has  resulted in the Iranian nuclear program, technology transfers by the  A.Q. Kahn network in Pakistan, and the wide proliferation of ballistic  missiles throughout the Middle East.  
Mr.  Olmert is right about one thing: Israel is a responsible nation, and  that caution extends to its nuclear program.  Available information  suggests that the Israelis have considered the use of nuclear weapons on  two occasions, during the 1967 Six-Day War, and again in 1973, during  the Dark Days of the Yom Kippur conflict with Syria and Egypt.   Surprised by the sudden Arab attack, Israeli lines crumbled, forcing  political leaders to weigh the nuclear option:
Defense  Minister Moshe Dayan, obviously not at his best at a press briefing,  was, according to Time magazine, rattled enough to later tell the prime  minister that “this is the end of the third temple,” referring to an  impending collapse of the state of Israel.  “Temple” was also the code  word for nuclear weapons.  
Prime  Minister Golda Meir and her “kitchen cabinet” made the decision on the  night of 8 October.  The Israelis assembled 13 twenty-kiloton atomic  bombs.  The number and in fact the entire story was later leaked by the  Israelis as a great psychological warfare tool.  Although most probably  plutonium devices, one source reports they were enriched uranium bombs.   The Jericho missiles at Hirbat Zachariah and the nuclear strike F-4s at  Tel Nof were armed and prepared for action against Syrian and Egyptian  targets.  They also targeted Damascus with nuclear capable long-range  artillery although it is not certain they had nuclear artillery shells.
Israel  nuclear forces were also on alert again during the first Gulf War in  1991, when Saddam’s SCUDs began targeting Israeli cities.  According to  U.S. Army Lt Col Warner Farr (who produced a lengthy study of Israel’s  nuclear capabilities in 1999), the Israelis extracted concessions from the U.S. in exchange for “staying out” of the conflict, and–at one point–actually tested a nuclear-capble missile, to pressure us to intensify our SCUD-hunting efforts. 
Fiftenn years later, faced with a growing menace from Iran, and continuing threats closer to home, Israel is likely expanding its nuclear arsenal, with the recent acquisition of Dolphin-class submarines, F-15I strike fighters, and the development of cruise missiles, all capable of delivering tactical nukes to distant targets. But those acquisitions–like Mr. Olmert’s televised faux pas–will renew the debate of just how public the Israeli nuclear program should be, and if the “non-admission” policy best serves the nation’s interests. If Monday’s post-interview spin is any indication, the current government apparently believes that the nuclear program should remain a badly-kept secret, to keep Israel’s enemies guessing about capabilities and intent. The practicality of maintaining that thin veil of secrecy is open to debate.
