But the clearest endorsement of terror as a legitimate instrument of political bargaining came from former President Jimmy Carter. In his book “Palestine: Peace Not Apartheid,” Mr. Carter appeals to the sponsors of suicide bombing. “It is imperative that the general Arab community and all significant Palestinian groups make it clear that they will end the suicide bombings and other acts of terrorism when international laws and the ultimate goals of the Road-map for Peace are accepted by Israel.” Acts of terror, according to Mr. Carter, are no longer taboo, but effective tools for terrorists to address perceived injustices.

Mr. Carter’s logic has become the dominant paradigm in rationalizing terror. When asked what Israel should do to stop Hamas’s rockets aimed at innocent civilians, the Syrian first lady, Asma Al-Assad, did not hesitate for a moment in her response: “They should end the occupation.” In other words, terror must earn a dividend before it is stopped.
