In general, the primary aim of this cleansing process is only to restore a certain sound and natural balance, and, secondly, to remove from official positions of national significance those elements to which one cannot entrust Germany's survival or destruction. For it will not be possible to avoid, in the next few years, [the need] to make sure that certain processes which must not be communicated to the rest of the world for reasons of the highest national interest, will indeed remain secret. This can only be guaranteed by the inner homogeneity of the administrative bodies concerned.
