SELECTIVE INTELLIGENCE.

They call themselves, self-mockingly, the Cabal--a small cluster of policy advisers and analysts now based in the Pentagon's Office of Special Plans. In the past year, according to former and present Bush Administration officials, their operation, which was conceived by Paul Wolfowitz, the Deputy Secretary of Defense, has brought about a crucial change of direction in the American intelligence community. These advisers and analysts, who began their work in the days after September 11, 2001, have produced a skein of intelligence reviews that have helped to shape public opinion and American policy toward Iraq. They relied on data gathered by other intelligence agencies and also on information provided by the Iraqi National Congress, or I.N.C., the exile group headed by Ahmad Chalabi. By last fall, the operation rivalled both the C.I.A. and the Pentagon's own Defense Intelligence Agency, the D.I.A., as President Bush's main source of intelligence regarding Iraq's possible possession of weapons of mass destruction and connection with Al Qaeda. As of last week, no such weapons had been found. And although many people, within the Administration and outside it, profess confidence that something will turn up, the integrity of much of that intelligence is now in question.

The director of the Special Plans operation is Abram Shulsky, a scholarly expert in the works of the political philosopher Leo Strauss. Shulsky has been quietly working on intelligence and foreign-policy issues for three decades; he was on the staff of the Senate Intelligence Com-mittee in the early nineteen-eighties and served in the Pentagon under Assistant Secretary of Defense Richard Perle during the Reagan Administration, after which he joined the Rand Corporation. The Office of Special Plans is overseen by Under-Secretary of Defense William Luti, a retired Navy captain. Luti was an early advocate of military action against Iraq, and, as the Administration moved toward war and policymaking power shifted toward the civilians in the Pentagon, he took on increasingly important responsibilities.

W. Patrick Lang, the former chief of Middle East intelligence at the D.I.A., said, "The Pentagon has banded together to dominate the government's foreign policy, and they've pulled it off. They're running Chalabi. The D.I.A. has been intimidated and beaten to a pulp. And there's no guts at all in the C.I.A.”

The hostility goes both ways. A Pentagon official who works for Luti told me, "I did a job when the intelligence community wasn't doing theirs. We recognized the fact that they hadn't done the analysis. We were providing information to Wolfowitz that he hadn't seen before. The intelligence community is still looking for a mission like they had in the Cold War, when they spoon-fed the policymakers.”

A Pentagon adviser who has worked with Special Plans dismissed any criticism of the operation as little more than bureaucratic whining. "Shulsky and Luti won the policy debate,"the adviser said. "They beat 'em--they cleaned up against State and the C.I.A. There's no mystery why they won--because they were more effective in making their argument. Luti is smarter than the opposition. Wolfowitz is smarter. They out-argued them. It was a fair fight. They persuaded the President of the need to make a new security policy. Those who lose are so good at trying to undercut those who won."He added, "I'd love to be the historian who writes the story of how this small group of eight or nine people made the case and won.”

According to the Pentagon adviser, Special Plans was created in order to find evidence of what Wolfowitz and his boss, Defense Secretary Donald Rumsfeld, believed to be true--that Saddam Hussein had close ties to Al Qaeda, and that Iraq had an enormous arsenal of chemical, biological, and possibly even nuclear weapons that threatened the region and, potentially, the United States.

Iraq's possible possession of weapons of mass destruction had been a matter of concern to the international community since before the first Gulf War. Saddam Hussein had used chemical weapons in the past. At some point, he assembled thousands of chemical warheads, along with biological weapons, and made a serious attempt to build a nuclear-weapons program. What has been in dispute is how much of that capacity, if any, survived the 1991 war and the years of United Nations inspections, no-fly zones, and sanctions that followed. In addition, since September 11th there have been recurring questions about Iraq's ties to terrorists. A February poll showed that seventy-two per cent of Americans believed it was likely that Saddam Hussein was personally involved in the September 11th attacks, although no definitive evidence of such a connection has been presented.
