If necessary, Israel must consider the use of pre emptive nuclear weapons as there is no precedent other than hitler for the existential threats emanating from Iran. Israel must not allow the anti semites to make them a canary in the coal mine as many 2000 year jew killers would like. The jewish people cannot take risks, those who threaten genocide must be destroyed first. It is better for jews to be the ones regretting using the weapons than being the ones annilated. That is what "never again" really means. It is not about convincing the jew killers to reform, it is about destroying them before they can destroy the jews. This is not PC but would guarantee a future for the jews.
