After the anthrax letter attacks of October 2001, the Bush administration pledged $57 billion to keep the nation safe from bioterror. Since then, the government has created a vast network of laboratories and institutions to track down and block every remotely conceivable form of bioterror threat.
The Obama administration seems committed to continuing the biodefense push, having just appointed a zealous bioterror researcher as undersecretary of science and technology in the Department of Homeland Security.
But is the threat really as great as we've been led to believe?
Last summer, the FBI concluded that the anthrax letters that killed five Americans came not from abroad but from an American laboratory, the United States Army Medical Research Institute of Infectious Diseases. Meanwhile, the Russian bioweapons program was officially shut down in 1992, and it's unlikely that anything remaining of it could pose much of a threat. Iraq, it has turned out, had no active program. And Al Qaeda's rudimentary explorations were interrupted, according to an Army War College report, by the U.S. invasion of Afghanistan.
So, you may be asking, who is the enemy and why we are spending so much trying to protect ourselves? Those are good questions, but don't expect government officials to be asking them any time soon.
Dr. Tara O'Toole, the administration's choice for the Homeland Security undersecretary of science and technology, is a fierce advocate of biodefense. In fact, her critics say, she is so dedicated to awakening people to the bioterror threat that she mangles facts and figures in a way that exaggerates the danger.
Especially troubling, they say, are two influential "tabletop exercises" O'Toole designed to model the impact -- and raise government awareness -- of the smallpox bioterror threat.
J. Michael Lane, former director of the Centers for Disease Control and Prevention's smallpox eradication program, is particularly troubled by one model called "Dark Winter," which was released in 2001. The model, he and others say, exaggerates the smallpox threat by assuming astoundingly high rates of transmission. "People get desperately sick before they are able to transmit the virus. They're knocked off their feet with high fevers and severe muscle pains before they're contagious," he explained. That means that each patient generally transmits the disease to just one or two others. Dark Winter used rates of 10 new infections for each patient, which meant the model predicted widespread infection and death from a smallpox attack.
