In reply to MikeTS:
I fully understand that this is an existential issue for you, but from here it is incredibly difficult to disentangle the propaganda emanating from all sides.
From here, while many of us remember the excesses of the Ayotollahs and the extremism that held sway after 1979, we are also presented with the image of a state whose people, mostly better educated, better informed and more prosperous than most in the region, are leaning towards a more secular, modern state; they want stability in the middle east as much (or more) than most.
From here, it doesn't seem that the Iranian state needs the destruction of Israel, as the unifying issue that transcends all others, in the way that Netanyahu seems to need Iran?
