Negotiating with terrorists

Jimmy Carter told Der Spiegel:

... fundamentalists believe they have a unique relationship with God, and that they and their ideas are God's ideas and God's premises on the particular issue. Therefore, by definition since they are speaking for God anyone who disagrees with them is inherently wrong. And the next step is: Those who disagree with them are inherently inferior, and in extreme cases -- as is the case with some fundamentalists around the world -- it makes your opponents sub-humans, so that their lives are not significant. Another thing is that a fundamentalist can't bring himself or herself to negotiate with people who disagree with them because the negotiating process itself is an indication of implied equality. [1]
