"A strike mission on the three nuclear facilities would require no fewer than 90 combat aircraft, including all 25 F-15Es in the IAF inventory and another 65 F-16I/Cs. On top of that, all the IAF's refueling planes will have to be airborne: 5 KC-130Hs and 4 B-707s. The combat aircraft will have to be refueled both en route to and on the way back from Iran. The IAF will have a hard time locating an area above which the tankers can cruise without being detected by the Syrians or the Turks.
One of the toughest operational problems to resolve is the fact that the facility at Natanz is buried deep underground. Part of it, the fuel-enrichment plant, reaches a depth of 8 meters, and is protected by a 2.5-meter-thick concrete wall, which is in turn protected by another concrete wall. By mid-2004 the Iranians had fortified their defense of the other part of the facility, where the centrifuges are housed. They buried it 25 meters underground and built a roof over it made of reinforced concrete several meters thick." Haaretz
This is a Haaretz article written by an Israeli journalist close to the IDF. Read it all, maybe twice. The basis for the article is a Cordesman study on the military feasibility of an Israeli effort against the Iranian Nuclear program.
The bottom line is simple. The Israelis "can't get there from here" without nuclear weapons and the thought of the consequences of that frightens them more than it does the Iranians.
Therefore, they have to persuade Obama to either cooperate with them in a massive operation that would not involve nuclear weapons or better yet (from their point of view) persuade Obama to make this an all US war against Iran.
Thus far, Israel's best asset in the effort to get what they want in regrd to Iran are the Iranians themselves. They have been unresponsive to President Obama's efforts to engage them in a dialogue leading to detente and they persist in bellicose rhetoric that reinforces the Israeli argument.
President Obama is not interested in doing Israel's bidding in regard to Iran, but continued Iranian intransigence could change that.
The Peace Process? Forget that. Bibi would rather die than see a Palestinian state come into being. pl
