The following passage seems to have been selectively quoted, and misconstrued, more than any other I have written:
"The link between belief and behavior raises the stakes considerably. Some propositions are so dangerous that it may even be ethical to kill people for believing them. This may seem an extraordinary claim, but it merely enunciates an ordinary fact about the world in which we live. Certain beliefs place their adherents beyond the reach of every peaceful means of persuasion, while inspiring them to commit acts of extraordinary violence against others. There is, in fact, no talking to some people. If they cannot be captured, and they often cannot, otherwise tolerant people may be justified in killing them in self-defense. This is what the United States attempted in Afghanistan, and it is what we and other Western powers are bound to attempt, at an even greater cost to ourselves and to innocents abroad, elsewhere in the Muslim world. We will continue to spill blood in what is, at bottom, a war of ideas."
This paragraph appears after a long discussion of the role that belief plays in governing human behavior, and it should be read in that context. Some critics have interpreted the second sentence of this passage to mean that I advocate simply killing religious people for their beliefs. Granted, I made the job of misinterpreting me easier than it might have been, but such a reading remains a frank distortion of my views. To someone reading the passage in context, it should be clear that I am discussing the link between belief and behavior. The fact that belief determines behavior is what makes certain beliefs so dangerous.
When one asks why it would be ethical to drop a bomb on Ayman al-Zawahiri, the current leader of al Qaeda, the answer cannot be, Because he killed so many people in the past. To my knowledge, the man hasnt killed anyone personally. However, he is likely to get a lot of innocent people killed because of what he and his followers believe about jihad, martyrdom, the ascendancy of Islam, etc. A willingness to take preventative action against a dangerous enemy is compatible with being against the death penalty (which I am). Whenever we can capture and imprison jihadists, we should. But in many cases this is either impossible or too risky. Would it have been better if we had captured Osama bin Laden? In my view, yes. Do I think the members of Seal Team Six should have assumed any added risk to bring him back alive? Absolutely not.
