But short of the compulsion of irresistible might, will any influence suffice to bring the enemies of to-day by their spontaneous choice into a European federation? Is any people, even the most pacific, prepared as yet to accept the surrender of sovereignty which entry into even a loosely-knit federation would involve? [Sidenote: A practicable dream.] The League of Peace presents itself to practical men as a dream capable of an early translation into fact. The allies need only agree to join their forces against any power which persisted, after offers of arbitration or mediation (a reservation which no old-fashioned alliance ever made) in attacking any one of them. It would differ from other alliances partly by its insistence on the duty of arbitration, partly by its frank and public constitution, but mainly by the ready welcome which it would offer even to the enemy of yesterday, should he elect to enter it. The United States would rally to it, seeing in it their best hope of safety, and ultimately it might become a genuine Pan-European League. It is sometimes suggested that Paine’s Anglo-Franco-American combination might form its nucleus. More often its advocates base their hopes on the Anglo-Franco-Russian entente, expanded by adhesion of some of the present neutrals. No one suggests, and this is the weakest point of the whole scheme, that Germany and Austria would be likely to join such a League at the start, though no one of this way of thinking would desire to exclude them. [Sidenote: The League must be more than the old alliances.]
