Or you can go one further and question the premise behind Israel's current public posture: that Iran really does pose an existential threat to Israel unknown since Hitler, and that this has to be dealt with before any deal with the Palestinians, and start your analysis all over.
Jeffrey Goldberg's essay sure does offer a lot of evidence for the power of the idea of an Iranian "Auschwitz" to scramble the rationality of the Israeli public and elites. And yet, oddly enough, his reported essay convinced me Israelis may - understandably - feel such a threat at a deep level but that most of the sane ones do not actually believe that an Iranian breakout capacity for a nuclear bomb would be the end of Zionism. And once you grasp this, the irrationalism of their intransigence on the West Bank becomes even starker.
Even Netanyahu rules out the idea of Tehran suddenly nuking Tel Aviv:
“Several bad results would emanate from this single development [Iran's nuclear bomb breakout]. First, Iran’s militant proxies would be able to fire rockets and engage in other terror activities while enjoying a nuclear umbrella. This raises the stakes of any confrontation that they’d force on Israel. Instead of being a local event, however painful, it becomes a global one. Second, this development would embolden Islamic militants far and wide, on many continents, who would believe that this is a providential sign, that this fanaticism is on the ultimate road to triumph."
We can, I think, roll our eyes a little at the latter fear. Jihadists, as we well know, can interpret anything as a providential sign of their eventual triumph. And the occupation of the West Bank is easily a more effective recruitment tool for largely Sunni terrorists to fight the West than a Shiite nuclear bomb. The former fear is, in contrast, perfectly legitimate, but not existential. Yes, a nuclear Iran would become even more emboldened - especially after the US spent a trillion dollars destroying the most viable counter-weight, Iraq. Yes, this could lead to some wealthy Arab states' appeasing the new regional power, or seeking their own nuclear balance; yes, it could galvanize Hezbollah and Hamas; and it could undermine confidence in Israel's long-term survival.
But none of that amounts to an existential threat - and that matters:
“The real threat to Zionism is the dilution of quality,” [Ehud Barak] said. “Jews know that they can land on their feet in any corner of the world. The real test for us is to make Israel such an attractive place, such a cutting-edge place in human society, education, culture, science, quality of life, that even American Jewish young people want to come here.” This vision is threatened by Iran and its proxies, Barak said. “Our young people can consciously decide to go other places,” if they dislike living under the threat of nuclear attack. “Our best youngsters could stay out of here by choice.”
If this truly is the real fear, then it seems to me, at best, highly hyperbolic to equate it with another Auschwitz. In fact, the whole scenario seems rather obviously manipulative. "If you don't bomb Iran, you'll be responsible for a Second Holocaust" is not the argument a sober and rational ally should make to its indispensable benefactor. It's a form of moral and emotional blackmail.
