By introducing conspiracy and chaos into the world, a terrorist hopes to make himself equal to the overwhelming world surrounding him. The idea isn’t to change history but to enact one’s dream life. The person who blows up the Boston marathon instantly becomes the equal of his act. What other mythic ambition can a loser instantly achieve, just by deciding to do it? “In America it is the individual himself, floating on random streams of disaffection, who tends to set the terms of the absurd,” DeLillo wrote. “Set the terms” is right: an individual terrorist creates the absurdity in which the rest of us have to live. Whether or not Oswald or the Tsarnaevs achieved what they hoped they would achieve, their dream lives now overlap with reality. Violence gives weight to the meaningless. “This is what guns are for, to bring balance to the world,” DeLillo wrote, speaking, once again, of Oswald.
