Courtesy of Milton Leitenberg’s research (“The Self-Fulfilling Prophecy of Bio-Terrorism” in the NONPROLIFERATION REVIEW, 16:1 (March 2009):

Annual deaths in the United States due to cancer: 565,000

Annual deaths in the United States due to tobacco: 440,000

Annual deaths in the United States due to obesity: 400,000

Annual deaths in the United States due to hospital infections: 99,000

Cumulative, global deaths due to bioterrorism: 5

I would add:

Cumulative, global deaths unrelated to Hiroshima and Nagasaki due to battlefield use of nuclear weapons: 0

Of course, the last two numbers could increase radically at any time. But they are strikingly low and incomprehensible, according to most of the literature on bioterrorism and nuclear dangers.
