After reading the whole thing through, the bottom line appears to be that doing serious damage, if not destroying, Iran's nuclear program infrastructure is technically and tactically feasible for Israel in the opinion of Larry Bond and his collaborators. In particular, Iran has very little military capability to stop an attack.
On the other hand, Israel needs to persuade at least one of the three powers controlling the air space on the way to Iraq to allow the air strikes to go forward because Iran's program is too extensive for a single air raid to do significant damage. So while the Israelis could certainly fly though the first time without permission, they'd need so many follow-up strikes that flying through without clearance isn't practical. Those three powers are the US (for Iraq air space) Turkey and Saudi Arabia. Bond's judgment is that Israel doesn't have the necessary level of support in any of the three. It's about getting that support and keeping it long enough to matter thant most of the game revolves. And here Iran does have come cards (literally) to play.
I'm definitely needing a partner to try this out. Any takers?
