The French newspaper Le Canard Enchainé reported dubious information coming from the French General Staff. According to the report, Israeli Chief of Staff Ashkenazi told his French counterpart that Israel plans to subvert Iranian nuclear facilities with commandos rather than bomb them. If so, the affair would greatly damage IAF’s prestige, demonstrating its inability to bypass Iranian air defenses.
The truth is probably just that Israel needs to use commandos to neutralize Iranian SAM batteries and clear the way for an IAF strike.
I believe this info was leaked for purposes of psychological warfare. Between advanced IAF avionics and cruise-missiles from Israeli subs, the Iranian air-defense network would be obliterated quickly. Israel would enjoy almost complete air-superiority. Hopefully Iran will let their pilots live by keeping those old “Tomcats” on the ground.
