In 1986, Congress authorized the chairman of the Joint Chiefs of Staff to act as the “principal military adviser” to the President. In this case, I was told, the current chairman, Marine General Peter Pace, has gone further in his advice to the White House by addressing the consequences of an attack on Iran. “Here’s the military telling the President what he can’t do politically”—raising concerns about rising oil prices, for example—the former senior intelligence official said. “The J.C.S. chairman going to the President with an economic argument—what’s going on here?” (General Pace and the White House declined to comment. The Defense Department responded to a detailed request for comment by saying that the Administration was “working diligently” on a diplomatic solution and that it could not comment on classified matters.)
A retired four-star general, who ran a major command, said, “The system is starting to sense the end of the road, and they don’t want to be condemned by history. They want to be able to say, ‘We stood up.’ ”
In late April, the military leadership, headed by General Pace, achieved a major victory when the White House dropped its insistence that the plan for a bombing campaign include the possible use of a nuclear device to destroy Iran’s uranium-enrichment plant at Natanz, nearly two hundred miles south of Tehran. The huge complex includes large underground facilities built into seventy-five-foot-deep holes in the ground and designed to hold as many as fifty thousand centrifuges. “Bush and Cheney were dead serious about the nuclear planning,” the former senior intelligence official told me. “And Pace stood up to them. Then the world came back: ‘O.K., the nuclear option is politically unacceptable.’ ” At the time, a number of retired officers, including two Army major generals who served in Iraq, Paul Eaton and Charles Swannack, Jr., had begun speaking out against the Administration’s handling of the Iraq war. This period is known to many in the Pentagon as “the April Revolution.”
“An event like this doesn’t get papered over very quickly,” the former official added. “The bad feelings over the nuclear option are still felt. The civilian hierarchy feels extraordinarily betrayed by the brass, and the brass feel they were tricked into it”—the nuclear planning—“by being asked to provide all options in the planning papers.”
