“Terrorist groups that employ suicide as a tactic follow a strategic logic to compel democratic governments to change their policies, but the motivations of the individual attackers have evolved over the past few years. In the London bombings of July 7, 2005, and in the failed plot to blow up airliners over the Atlantic uncovered in August 2006, the actual and prospective suicide terrorists were not personally suffering under foreign occupation, but they did sympathize with the plight of a kindred group. Deep anger at the use of foreign combat forces to suppress national self-determination by kindred groups is sufficient to inspire self-sacrifice even when personal motives for revenge are completely absent.”
