THE IRAN PLANS
Would President Bush go to war to stop Tehran from getting the bomb?

The Bush Administration, while publicly advocating diplomacy in order to stop Iran from pursuing a nuclear weapon, has increased clandestine activities inside Iran and intensified planning for a possible major air attack. Current and former American military and intelligence officials said that Air Force planning groups are drawing up lists of targets, and teams of American combat troops have been ordered into Iran, under cover, to collect targeting data and to establish contact with anti-government ethnic-minority groups. The officials say that President Bush is determined to deny the Iranian regime the opportunity to begin a pilot program, planned for this spring, to enrich uranium.

American and European intelligence agencies, and the International Atomic Energy Agency (I.A.E.A.), agree that Iran is intent on developing the capability to produce nuclear weapons. But there are widely differing estimates of how long that will take, and whether diplomacy, sanctions, or military action is the best way to prevent it. Iran insists that its research is for peaceful use only, in keeping with the Nuclear Non-Proliferation Treaty, and that it will not be delayed or deterred.

There is a growing conviction among members of the United States military, and in the international community, that President Bush’s ultimate goal in the nuclear confrontation with Iran is regime change. Iran’s President, Mahmoud Ahmadinejad, has challenged the reality of the Holocaust and said that Israel must be “wiped off the map.” Bush and others in the White House view him as a potential Adolf Hitler, a former senior intelligence official said. “That’s the name they’re using. They say, ‘Will Iran get a strategic weapon and threaten another world war?’ ”

A government consultant with close ties to the civilian leadership in the Pentagon said that Bush was “absolutely convinced that Iran is going to get the bomb” if it is not stopped. He said that the President believes that he must do “what no Democrat or Republican, if elected in the future, would have the courage to do,” and “that saving Iran is going to be his legacy.”

One former defense official, who still deals with sensitive issues for the Bush Administration, told me that the military planning was premised on a belief that “a sustained bombing campaign in Iran will humiliate the religious leadership and lead the public to rise up and overthrow the government.” He added, “I was shocked when I heard it, and asked myself, ‘What are they smoking?’ ” ...

...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....

...The lack of reliable intelligence leaves military planners, given the goal of totally destroying the sites, little choice but to consider the use of tactical nuclear weapons. “Every other option, in the view of the nuclear weaponeers, would leave a gap,” the former senior intelligence official said. “ ‘Decisive’ is the key word of the Air Force’s planning. It’s a tough decision. But we made it in Japan.”

He went on, “Nuclear planners go through extensive training and learn the technical details of damage and fallout—we’re talking about mushroom clouds, radiation, mass casualties, and contamination over years. This is not an underground nuclear test, where all you see is the earth raised a little bit. These politicians don’t have a clue, and whenever anybody tries to get it out”—remove the nuclear option—“they’re shouted down.”...

...The attention given to the nuclear option has created serious misgivings inside the offices of the Joint Chiefs of Staff, he added, and some officers have talked about resigning. Late this winter, the Joint Chiefs of Staff sought to remove the nuclear option from the evolving war plans for Iran—without success, the former intelligence official said. “The White House said, ‘Why are you challenging this? The option came from you.’ ”

The Pentagon adviser on the war on terror confirmed that some in the Administration were looking seriously at this option, which he linked to a resurgence of interest in tactical nuclear weapons among Pentagon civilians and in policy circles. He called it “a juggernaut that has to be stopped.” He also confirmed that some senior officers and officials were considering resigning over the issue. “There are very strong sentiments within the military against brandishing nuclear weapons against other countries,” the adviser told me. “This goes to high levels.” ...

...The Administration’s case against Iran is compromised by its history of promoting false intelligence on Iraq’s weapons of mass destruction. In a recent essay on the Foreign Policy Web site, entitled “Fool Me Twice,” Joseph Cirincione, the director for nonproliferation at the Carnegie Endowment for International Peace, wrote, “The unfolding administration strategy appears to be an effort to repeat its successful campaign for the Iraq war.”...

...The adviser went on, “If we go, the southern half of Iraq will light up like a candle.” The American, British, and other coalition forces in Iraq would be at greater risk of attack from Iranian troops or from Shiite militias operating on instructions from Iran. (Iran, which is predominantly Shiite, has close ties to the leading Shiite parties in Iraq.) A retired four-star general told me that, despite the eight thousand British troops in the region, “the Iranians could take Basra with ten mullahs and one sound truck.”...
