The greatest value of the atomic bomb, after its compulsory prevention of war, is its compulsory abolition of frontiers. It renders them meaningless. It makes a world authority inevitable. It renders a merely international league insufficient. Only a world federation and world authority will suffice to meet it. With this change in media, all military manuals became obsolete overnight. What gunpowder did to the bow and arrow, atomic bombs have done to gunpowder. The political struggle to secure strategic frontiers has now lost all meaning. For there are none.
