Any new Israeli government is now legally required to prepare a codified national security strategy within 150 days of its official formation. Though nuclear doctrine and strategy will likely be limited to the highest security-level classifications, nothing could have greater existential impact for Israel. Moreover, at a time when the principal threats to Israel are coming from a still pre-nuclear Iran and certain sub-state proxies, the National Security Council will have to consider wider and more explicit applications of nuclear deterrence. Israel’s decision-makers will need to undertake incremental but prompt shifts from “deliberate nuclear ambiguity” to “selective nuclear disclosure.” Otherwise, Jerusalem will have to accept a strategic reality in which Iran and other adversaries continuously threaten Israel with non-nuclear but high-lethality ballistic missiles and/or chemical-biological (CBW) ordnance – an unsustainable reality of interminable war.
