“That’s true only if Israel uses nukes”
Israel can wreck considerable damage on Iran with targeted attacks. Of course, they do not have the ability to cripple them without nukes.
But they can take out communications, water, electric and some strategic IRG facilities, maybe leaders.
The only thing Iran can do about it is to launch inaccurate missiles back at Israel. And if they DARE top one with chemicals or biologicals, they will then be promptly nuked.
Israel may wish to provoke them to WMD. And they can do so by shaming them to the people of Iran. They can do this by carrying out these attacks over weeks and months.
Don’t put it beyond Mossad to position trucks full of explosives in various disguises parked next to targets in Iran and detonate from afar. ( Israelis don’t do suicide bombing). It would be absolutely suicidal for Iran to initiate a missile launch on Israel. BTW, it would take Israeli intelligence about 3 seconds to detect a launch, know exactly the type of missile launched and who was responsible for the launch. The big question is do the Israelis know the locations of Iranian missile batteries in Syria and can they destroy them when they are being prepared for launch.
