THE IRANIAN NUCLEAR THREAT:
THE MILITARY OPTION

The Iran Attack Plan
ANTHONY H. CORDESMAN

.. .Israel's political and military leaders have long made it clear that they are considering taking decisive military action if Iran continues to develop its nuclear program .... Reporting by the International Atomic Energy Agency ... has made it clear that whether or not Iran ties all of its efforts into a fennal nuclear weapons program. it has acquired all of the elements necessary to make and deliver such weapons ... , Iran has acquired North Korean and other nuclear weapons design data through sources like the sales network once led by the former head of Pakistan's nuclear program, A. Q. Khan. Iran has all of the technology and production and manufacturing capabilities needed for fission weapons.... It has also worked on nuclear weapons designs for missile warheads. These capabilities are dispersed in many facilities in many cities and
remote areas, and often into many buildings in each facility---each of which would have to be a target in
an Israeli military strike.

It is far from certain that such action would be met with success .... One of the fundamental problems dogging Israel, especially concerning short-ranged fighters and fighter-bombers, is distance. Iran's potential targets are between 950 and 1,400 miles from Israel, the far margin of the ranges Israeli fighters can reach, even with aerial refueling. Israel would be hard-pressed to destroy all of Iran's best-known targets. What's more, Iran has had years in which to build up covert facilities, disperse elements of its nuclear and missile programs, and develop options for recovering from such an attack.

At best, such action would delay Iran's nuclear buildup. It is more likely to provoke the country into accelerating its plans. Either way, Israel would have to contend with the fact that it has consistently had a "red light" from both the Bush and Obama administrations opposing such strikes. Any strike that overflew
Arab tertitory or attacked a fellow Islamic state would stir the ire of neighboring Arab states, as well as Russia, China and several European states.

This might not stop Israel. Hardly a week goes by without another warning from senior Israeli officials that a military strike is possible, and that Israel cannot tolerate a nuclear-armed Iran, even though no nation has indicated it would support such action ....

Most analyses of a possible Israeli attack focus on only three of Iran's most visible facilities: its centrifuge facilities at Natanz, its light water nuclear power reactor near Bushehr, and a heavy water reactor at Arak it could use to produce plutonium. They are all some 950 to 1,000 miles from Israel. Each of these three targets differs sharply in terms of the near-term risk it poses to Israel and its vulnerability.

Israel has fighters, refueling tankers and precision-guided air-to-ground weapons to strike at all of these targets---even if it flies the long-distance routes needed to avoid the most critical air defenses in neighboring Arab states .... In August 2003, the Israeli Air Force demonstrated the strategic capability to strike far-off targets such as Iran by flying three F-15 jets to Poland, 1,600 nautical miles away. Israel can launch and refuel two to three full squadrons of combat aircraft for a single set of strikes against Iran, and provide suitable refueling. 'Israel could also provide fighter escorts and has considerable electronic-warfare capability to suppress Iran's aging air defenses. It might take losses to Iran's fighters and surface-to-air missiles, but such losses would probably be limited.

Israel would, however, still face two critical problems. The first would be whether it can destroy a hardened underground facility like Natanz. The second is that a truly successful strike might have to hit far more targets over a much larger area than the three best known sites. Iran has had years to build up covert and dispersed
facilities, and is known to have dozens of other facilities associated with some aspect of its nuclear programs ....

Experts sharply disagree as to whether the Israeli air force could do more than limited damage to the key Iranian facility at Nalanz. Some feel it is too deeply underground and too hardened for Israel to have much impact. Others believe that it is more vulnerable than conventional wisdom has it, and Israel could use weapons like the GBU-28 earth-penetrating bombs it has received from the U.S. or its own penetrators....
Many of Iran's known facilities present the added problem that they are located among civilian facilities and peaceful nuclear-research activities- although Israel's precision-strike capabilities may well be good enough to allow it to limit damage to nearby civilian facilities ....

Israel also faces limits on its military capabilities .... Israel does not have the density and quality of intelligence assets necessary to reliably assess the damage done to a wide range of small and disperse targets and to detect new Iranian efforts.

These problems are why a number of senior Israeli intelligence experts and military officers feel that Israel should not strike Iran, although few would recommend that Israel avoid using the threat of such strikes to help U.S. and other diplomatic efforts to persuade Iran to halt....

The alternatives, however, are not good for Israel, the U.S., Iran's neighbors or Arab neighbors. Of course being attacked is not good for Iran. Israel could still strike, if only to try to buy a few added years of time. Iranian persistence in developing nuclear weapons could push the U.S. into launching its own strike on
Iran-although either an Israeli or U.S. strike might be used by Iran's hardliners to justify an all-out nuclear arms race ....

Israel will not wait passively as Iran develops a nuclear capability. Like several Arab states, Israel already is developing better missile and air defenses, and more-advanced forms of its Arrow ballistic missile defenses.... [P]rovoking its Arab neighbors and Turkey into developing their nuclear capabilities, or the U.S. into
offering them a nuclear umbrella targeted on Iran, could create additional threats .... Iran's search for nuclear-armed missiles may well unite its neighbors against it as well as create a major new nuclear threat to its survival.
