We were once told that the aeroplane had ‘abolished frontiers’; actually it is only since the aeroplane became a serious weapon that frontiers have become definitely impassable. The radio was once expected to promote international understanding and co-operation; it has turned out to be a means of insulating one nation from another. The atomic bomb may complete the process by robbing the exploited classes and peoples of all power to revolt, and at the same time putting the possessors of the bomb on a basis of military equality. Unable to conquer one another, they are likely to continue ruling the world between them, and it is difficult to see how the balance can be upset except by slow and unpredictable demographic changes.
