Seymour Hersh on war plans against Iran

Last month, in a paper given at a conference on Middle East security in Berlin, Colonel Sam Gardiner, a military analyst who taught at the National War College before retiring from the Air Force, in 1987, provided an estimate of what would be needed to destroy Iran’s nuclear program. Working from satellite photographs of the known facilities, Gardiner estimated that at least four hundred targets would have to be hit. He added:

I don’t think a U.S. military planner would want to stop there. Iran probably has two chemical-production plants. We would hit those. We would want to hit the medium-range ballistic missiles that have just recently been moved closer to Iraq. There are fourteen airfields with sheltered aircraft. . . . We’d want to get rid of that threat. We would want to hit the assets that could be used to threaten Gulf shipping. That means targeting the cruise-missile sites and the Iranian diesel submarines. . . . Some of the facilities may be too difficult to target even with penetrating weapons. The U.S. will have to use Special Operations units.

One of the military’s initial option plans, as presented to the White House by the Pentagon this winter, calls for the use of a bunker-buster tactical nuclear weapon, such as the B61-11, against underground nuclear sites. One target is Iran’s main centrifuge plant, at Natanz, nearly two hundred miles south of Tehran. Natanz, which is no longer under I.A.E.A. safeguards, reportedly has underground floor space to hold fifty thousand centrifuges, and laboratories and workspaces buried approximately seventy-five feet beneath the surface. That number of centrifuges could provide enough enriched uranium for about twenty nuclear warheads a year. (Iran has acknowledged that it initially kept the existence of its enrichment program hidden from I.A.E.A. inspectors, but claims that none of its current activity is barred by the Non-Proliferation Treaty.) The elimination of Natanz would be a major setback for Iran’s nuclear ambitions, but the conventional weapons in the American arsenal could not insure the destruction of facilities under seventy-five feet of earth and rock, especially if they are reinforced with concrete.

There is a Cold War precedent for targeting deep underground bunkers with nuclear weapons. In the early nineteen-eighties, the American intelligence community watched as the Soviet government began digging a huge underground complex outside Moscow. Analysts concluded that the underground facility was designed for “continuity of government�—for the political and military leadership to survive a nuclear war. (There are similar facilities, in Virginia and Pennsylvania, for the American leadership.) The Soviet facility still exists, and much of what the U.S. knows about it remains classified. “The ‘tell’ �—the giveaway—“was the ventilator shafts, some of which were disguised,� the former senior intelligence official told me. At the time, he said, it was determined that “only nukes� could destroy the bunker. He added that some American intelligence analysts believe that the Russians helped the Iranians design their underground facility. “We see a similarity of design,� specifically in the ventilator shafts, he said.
