Claimed responsibility for attacks both signals power and recruits adherents

Evidence

Suicide bombers are heralded as martyrs; some families even take pride in offspring who sacrifice their lives in defense of Islam. Claiming responsibility for death and destruction also serves another important function. Well-organized terrorist operations use destructive exploits as a show of power over their enemies. These successes strengthen the motivation to forge ahead with their cause and to attract recruits (Kydd & Walter, 2006). — Albert Bandura, Moral Disengagement, 2154
