Clearly, it is not German militarism alone, but militarism in general that must be broken. The real question is how to change the inner attitude of nations, their beliefs and feelings towards one another, so as to make each nation and its rulers recognize that it is no longer either desirable or feasible to seek peculiar advantages for itself by bringing force to bear upon another nation. But it may be urged, granted that disarmament may not be set afoot spontaneously and separately by the different nations, mutual disarmament can occur by arrangement between the Powers, which, after the menace of German aggression is removed, will be disposed to take this step in concert. Such disarmament, it is usually conceived, will not stand alone, but will form an important feature of a larger international policy, by which the Powers will agree among themselves to settle any differences that may arise by reference to courts of conciliation or of arbitration, and perhaps also to concert measures of common action in dealing with States and territories not within their jurisdiction. Such a concert of European Powers has hitherto appeared to many to yield an adequate basis for the peace of Europe, if it could be brought about. It has also seemed to most men the utmost limit of the actually attainable. The idea of the possibility of any closer relation between sovereign independent States has been dismissed as chimerical.
