Today, of course, they and many other known weapons are still unaccounted for. Does it follow, therefore, that they never existed? Or does it make more sense to conclude that the weapons were there and that either we'll find them or we'll find out what happened to them?

The answer depends on how broad and pervasive you like your conspiracies to be. Because if Bush and British Prime Minister Tony Blair are lying, they're not alone. They're part of a vast conspiratorial network of liars that includes U.N. weapons inspectors and reputable arms control experts both inside and outside government, both Republicans and Democrats.

Maybe former CIA director John Deutch was lying when he testified before the Senate Intelligence Committee on Sept. 19, 1996, that "we believe that [Hussein] retains an undetermined quantity of chemical and biological agents that he would certainly have the ability to deliver against adversaries by aircraft or artillery or by Scud missile systems."

Maybe former defense secretary William Cohen was lying in April when he said, "I am absolutely convinced that there are weapons. . . . I saw evidence back in 1998 when we would see the inspectors being barred from gaining entry into a warehouse for three hours with trucks rolling up and then moving those trucks out."

Maybe the German intelligence service was lying when it reported in 2001 that Hussein might be three years away from being able to build three nuclear weapons and that by 2005 Iraq would have a missile with sufficient range to reach Europe.

Maybe French President Jacques Chirac was lying when he declared in February that there were probably weapons of mass destruction in Iraq and that "we have to find and destroy them."

Maybe Al Gore was lying when he declared last September, based on what he learned as vice president, that Hussein had "stored secret supplies of biological and chemical weapons throughout his country."

Finally, there's former president Bill Clinton. In a February 1998 speech, Clinton described Iraq's "offensive biological warfare capability, notably 5,000 gallons of botulinum, which causes botulism; 2,000 gallons of anthrax; 25 biological-filled Scud warheads; and 157 aerial bombs." Clinton accurately reported the view of U.N. weapons inspectors "that Iraq still has stockpiles of chemical and biological munitions, a small force of Scud-type missiles, and the capacity to restart quickly its production program and build many, many more weapons." That was as unequivocal and unqualified a statement as any made by George W. Bush.

Clinton went on to insist, in words now poignant, that the world had to address the "kind of threat Iraq poses . . . a rogue state with weapons of mass destruction, ready to use them or provide them to terrorists . . . who travel the world among us unnoticed." I think Bush said that, too.

So if you like a good conspiracy, this one's a doozy. And the best thing about it is that if all these people are lying, there's only one person who ever told the truth: Saddam Hussein. And now we can't find him either.
