The recruits undergo intense religious indoctrination, attend lectures, and undertake long fasts. The week before the bombing, the volunteers are watched closely by two Hamas activists for any signs of wavering, according to Nasra Hassan, writing in The New Yorker. Shortly before the “sacred explosion,” as Hamas calls it, the bomber records a video testament. To draw inspiration, he watches this video and the videos made by his predecessors repeatedly and then sets off for his would-be martyrdom after performing a ritual ablution and donning clean clothes. The bombers are assured by Hamas clerics that their deaths will be painless and that they will be met in paradise by dozens of virgins. The cost of the average bombing itself runs around $150.
