What was a surprise was the notion that they'd use nukes. That, incidentally, is the reason I thought the Israeli leak had some credibility. If they'd leaked that they were planning a conventional strike, I'd have thought it was just a smoke screen. I've been saying for a couple of years now that a conventional strike won't do it. Only a nuke strike will do it. So the fact that Israel now comes out and proposes it suggests to me that it's not just talk. They've actually done the engineering. And I think that Tehran has figured that out as well.
I suspect that Iran's plan is to complete their nuke program *before* Israel realizes it...or hope that,in the end,Israel will lose its nerve.
