“Death Sentence For Israel”
Death sentence for Iran, also. Israel very likely has a developed second-strike capability and due to the concentration of populations in large cities in the Arab world, my guess would be that only a few Bedouins would be left working the deserts, wondering where the heck everyone went. This is probably why the Saudis would rather take care of the problem themselves.
Depends how much time to launch, also put in mind it takes a small fraction of a time for a short-range missile from Iran to hit Israel as opposed to a Russian missile travelling the many thousands of miles to hit a U.S. target. If Iran ever does launch a missile, Israel likely won’t even have time to react or launch any of their own.
