Other than 175 grains of Pb, that seems the only way to stop terrorists.
Early in his career, Arafat set up a very effective terrorist group (IIRC, "Black November"). Having completed their tasks, Arafat faced the problem of "turning off" a highly motivated & dangerous group. He did so by seeking out the most beautiful & desireable young single Palestinean women, and persuading them to serve their people by marrying these "heros". Upon nuptuals, the terrorists suddenly became very docile and domesticated, and ceased their lethal activities.
Give these people something to live for, and they won't want to die in a blaze of glory. (Until then, 175gr@2300fps.)
