The question being left somewhat at loose ends, whether the projected league is to include the two or three Imperial Powers whose pacific intentions are, euphemistically, open to doubt.
Such is the outline of the project and its premises.

An attempt to fill in this outline will, perhaps, conduce to an appreciation of what is sought and of what the conditioning circumstances will enforce in the course of its realisation.

As touches the fear of aggression, it has already been indicated, perhaps with unnecessary iteration, that these two Imperial Powers are unable to relinquish the quest of dominion through warlike enterprise, because as dynastic States they have no other ulterior aim; as has abundantly appeared in the great volume of expository statements that have come out of the Fatherland the past few years, official, semi-official, inspired, and spontaneous.

"Assurance of the nation's future" is not translatable into any other terms.

The Imperial dynasty has no other ground to stand on, and can not give up the enterprise so long as it can muster force for any formidable diversion, to get anything in the way of dominion by seizure, threat or chicane.
This is coming to be informally and loosely, but none the less definitively, realised by the pacific nations; and the realisation of it is gaining in clearness and assurance as time passes.
