From Jeff Goldberg’s article about the possibility of an Israeli attack on Iran:
After staring at the photograph of the Israeli air-force flyover of Auschwitz more than a dozen different times in more than a dozen different offices, I came to see the contradiction at its core. If the Jewish physicists who created Israel’s nuclear arsenal could somehow have ripped a hole in the space-time continuum and sent a squadron of fighters back to 1942, then the problem of Auschwitz would have been solved in 1942. In other words, the creation of a serious Jewish military capability—a nuclear bomb, say, or the Israeli air force—during World War II would have meant a quicker end to the Holocaust. It is fair to say, then, that the existence of the Israeli air force, and of Israel’s nuclear arsenal, means axiomatically that the Iranian nuclear program is not the equivalent of Auschwitz.
On the other hand, Israeli author Daniel Gordis argues that an Iranian nuclear weapon would restore the conditions of Jewish vulnerability before the founding of Israel:
What must be understood is that the threat to Israel is not that Iran will one day use the bomb. No, Iran merely needs to possess the bomb to undermine the central purpose of Israel’s existence—and in so doing, to reverse the dramatic change in the existential condition of the Jews that 62 years of Jewish sovereignty has wrought. The mere possession of a nuclear weapon by Iran would instantly restore Jews to the status quo ante before Jewish sovereignty, to a condition in which their futures would depend primarily on the choices their enemies—and not Jews themselves—make.
My thought about this after reading Gordis’ article was that Israel is not unique in this fear. Goldberg linked to James Fallows’ reaction to the article, in which Fallows writes that nuclear weapons threaten all people with destruction, not just Israelis.
