Mechanized warfare still left room for human qualities to play an important part in the issue. ‘Automatic warfare’ cancels them out, except in a passive form. Archidamus is at last being justified. Courage, skill and patriotism become shrinking assets. The most virile nation might not be able to withstand another, inferior to it in all natural qualities, if the latter had some decisively superior technical appliance.
(...)The advent of ‘automatic warfare’ should make plain the absurdity of warfare as a means of deciding nations’ claims to superiority. It blows away romantic vapourings about the heroic virtues of war, utilized by aggressive and ambitious leaders to generate a military spirit among their people. They can no longer claim that war is any test of a people’s fitness, or even of its national strength. Science has undermined the foundations of nationalism, at the very time when the spirit of nationalism is most rampant.
