This is not an easy situation for Israel.
Israel's goal would be to surgically destroy the reactors.
Iran, on the other hand, would seek to wipe out Israel.
I believe the Iron Dome to be suspect; maybe it can destroy a few
missiles, but if Iran fired volley after volley of missiles,
some would score direct hits on dense urban centers.
Then what? Bear in mind, Israel has close to a dozen nuclear subs
along with the most advanced jets the US has to offer.
What choice would Israel have but to to retaliate?
We're talking about millions of dead Iranians.
That simply is not supposed to happen. In the final analysis,
the two countries will have to learn to live with one another.
