I think they know a lot more about the Iran/Israel situation, and fear that an IDF attack on Iranian nuke sites will lead to a regional missile exchange, and then all bets are off. That’s my guess.
The Israelies mean it when they say, “Never Again.” They will attack before Iran puts nuclear warheads atop missiles. And then the genie will be out of the bottle.
That is my dos centavos.
If there is time, I recommend a book about this very scenario unfolding. Your literature is well recieved in the community, and this is one good way to put that scenario out there.
