WASHINGTON -- President Bush secretly ordered a war plan drawn up against Iraq less than two months after U.S. forces attacked Afghanistan in 2001 and was so worried the decision would cause a furor he did not tell everyone on his national security team, says a new book on his Iraq policy.

Bush feared that if news got out about the Iraq plan as U.S. forces were fighting another conflict, people would think he was eager for war, journalist Bob Woodward writes in "Plan of Attack," a behind-the-scenes account of the 16 months leading to the Iraq invasion.

Bush did not address those preparations when asked about them Friday, saying, "I do know that it was Afghanistan that was on my mind and I didn't really start focusing on Iraq 'til later on."

Spokesman Scott McClellan confirmed Bush talked to Defense Secretary Donald H. Rumsfeld about Iraq war preparations during the Afghan campaign but said that did not mean the president was set on a course for invading Iraq at that time.

The Associated Press obtained a copy of the book, which will be available in bookstores next week. Woodward will be interviewed on CBS' "60 Minutes" Sunday night.

"I knew what would happen if people thought we were developing a potential war plan for Iraq," Bush is quoted as telling Woodward. "It would look like that I was anxious to go to war. And I'm not anxious to go to war."

Bush and his aides have denied accusations they were preoccupied with Iraq at the cost of paying attention to the al-Qaida terrorist threat before the Sept. 11, 2001, attacks. A commission investigating the attacks just concluded several weeks of public testimony from high-ranking government officials. One of them, former counterterrorism chief Richard Clarke, charged the Bush administration's determination to invade Iraq undermined the war on terror.

Woodward's account fleshes out the degree to which some members of the administration were focused on Saddam Hussein from the onset of Bush's presidency and even after the terrorist attacks made the destruction of al-Qaida the top priority.

Woodward says Bush pulled Defense Secretary Donald H. Rumsfeld aside Nov. 21, 2001 -- when U.S. forces and allies were in control of about half of Afghanistan -- and asked him what kind of war plan he had on Iraq. When Rumsfeld said it was outdated, Bush told him to get started on a fresh one.

Bush said Friday the subject of Iraq came up four days after the terrorist attacks when he met his national security team at Camp David to discuss a response to the assault. "I said let us focus on Afghanistan," he said, taking questions after a meeting with British Prime Minister Tony Blair.

Asked about the Nov. 21 meeting with Rumsfeld in a cubbyhole office adjacent to the Situation Room, Bush said only, "I can't remember exact dates that far back."

The book says Bush told Rumsfeld to keep quiet about their planning and when the defense secretary asked to bring CIA director George Tenet into it at some point, the president said not to do so yet.

Even Bush's national security adviser, Condoleezza Rice, was apparently not fully briefed. Woodward said Bush told her that morning he was having Rumsfeld work on Iraq but did not give details.

The Bush administration's drive toward war with Iraq raised an international furor anyway, alienating longtime allies who did not believe the White House had made a sufficient case against Saddam. Saddam was toppled a year ago and taken into custody last December. But the central figure of al-Qaida, Osama bin Laden, remains at large and a threat to the west.

The book says Gen. Tommy Franks, who was in charge of the Afghan war as head of Central Command, uttered a string of obscenities when the Pentagon told him to come up with an Iraq war plan in the midst of fighting another conflict.

Woodward, a Washington Post journalist who wrote an earlier book on Bush's anti-terrorism campaign and broke the Watergate scandal with Carl Bernstein, says Cheney's well-known hawkish attitudes on Iraq were frequently decisive in Bush's decision-making.

Cheney pressed the outgoing Clinton administration to brief Bush on the Iraq threat before he took office, Woodward writes.

In August 2002, when Bush talked publicly of being a patient man who would weigh Iraqi options carefully, the vice president took the administration's Iraq policy on a harder track in a speech declaring the weapons inspections ineffective. Cheney's speech was viewed as the beginning of a campaign to undermine or overthrow Saddam. Woodward said Bush let Cheney make the speech without asking what he would say.

The vice president also figured prominently in a protracted decision March 19, 2003, to strike Iraq before a 48-hour ultimatum for Saddam Hussein to leave the country had expired.

When the CIA and its Iraqi sources reported that Saddam's sons and other family members were at a small palace, and Saddam was on his way to join them, Bush's top advisers debated whether to strike ahead of plan.

Franks was against it, saying it was unfair to move before a deadline announced to the other side, the book says. Rumsfeld and Rice favored the early strike, and Secretary of State Colin Powell leaned that way.

But Bush did not make his decision until he had cleared everyone out of the Oval Office except the vice president. "I think we ought to go for it," Cheney is quoted as saying. Bush did.

U.S. forces unleashed bombs and cruise missiles, blanketing the compound but missing the palace. Tenet called the White House before dawn to say the Iraqi leader had been killed. But his optimism was premature. Saddam was alive.
