Dave: the problem with relying on the Israelis for this is that their airpower is severely limited by lack of tanker aircraft. I'm sure they'd like to do the required job on Iran, but the Iranian nuke facilities are dispersed, hardened, and not susceptible of short-range aircraft attack. And once the Russian double-digit SAMs are in place Israel will be out of options. They can't spell B-2 over there. Stealth is the answer. Now, what was the question?
On the other hand, remember the Brit SBS motto: if not by strength, then guile.
