Charles Darwin wrote that "It's not the strongest of the species that survives, nor the most intelligent, but the one most responsive to change."
It is a lesson that has gone unlearnt in Israel.
We continue threatening to use force and opting for military solutions as we always have. As if nothing changes. As if the Middle East hasn't been turned upside-down by the so-called Arab Spring and Syria isn't imploding on our doorstep. As if an Islamic country, Pakistan, doesn't already have nuclear capability and the entirety of Israel isn't within the range of thousands of missiles from far and near.
The only change to which we appear to be responsive is the minutiae of political and diplomatic developments in Washington. When it comes to Washington, our feelers are exquisitely sensitive, quivering wildly at every whisper and nuance. But, even there, our actions are true to type: we badger, we subvert administrations if we don't like them and, if we don't get what we want, we resort to blackmail. Just as we've always done.
Iran is the latest Darwinian challenge to Israel's ability to react to change.
Despite the dramatic rhetoric of the prime minister and his dummy the defense minister, the current bout of war hysteria has nothing to do with imminent danger from Iran. No-one with half a brain honestly believes that Iran is going to attack Israel with nuclear weapons - not now, not next year and not in the conceivable future. Bibi doesn't believe it and even Ehud Barak, the man who turned paranoia into an art form, doesn't believe it, though it serves his self-aggrandizing purposes to pretend he does.
