‘Abdu’l-Baha elaborates on the need to create a “binding treaty, and…a covenant” among “all the governments on earth”

“The sovereigns of the world,” writes ‘Abdu’l Bahá in elaboration of this theme, “must conclude a binding treaty, and establish a covenant, the provisions of which shall be sound, inviolable and definite. They must proclaim it to all the world, and obtain for it the sanction of all the human race… All the forces of humanity must be mobilized to insure the stability and permanence of this Most Great Covenant… The fundamental principle underlying this solemn Pact should be so fixed that if any government later violate any one of its provisions, all the governments on earth should arise to reduce it to utter submission, nay the human race as a whole should resolve, with every power at its disposal, to destroy that government.”

1936: Bahá’u’lláh’s “prophetic…words…in the light of recent international developments”

How clear, how prophetic, must sound the words uttered by Bahá’u’lláh in the light of recent international developments:—“Be united, O concourse of the sovereigns of the world, for thereby will the tempest of discord be stilled amongst you, and your peoples find rest. Should any one among you take up arms against another, rise ye all against him, for this is naught but manifest justice.” “The time must come,” He, foreshadowing the tentative efforts that are now being made, has written, “when the imperative necessity for the holding of a vast, an all-embracing assemblage of men will be universally realized. The rulers and kings of the earth must needs attend it, and, participating in its deliberations, must consider such ways and means as will lay the foundations of the world’s Great Peace among men… Should any king take up arms against another, all should unitedly arise and prevent him.”

1936: “For the first time in the history of humanity the system of collective security, foreshadowed by Bahá’u’lláh and explained by ‘Abdu’l Bahá, has been seriously envisaged, discussed and tested.”

A general Pact on security has been the central purpose towards which these efforts have, ever since the League was born, tended to converge. The Treaty of Guarantee which, in the initial stages of its development, its members had considered and discussed; the debate on the Geneva Protocol, the discussion of which, at a later period, aroused among the nations, both within the League and outside it, such fierce controversy; the subsequent proposal for a United States of Europe and for the economic unification of that continent; and last but not least the policy of sanctions initiated by its members, may be regarded as the most significant landmarks in its checkered history. That no less than fifty nations of the world, all members of the League of Nations, should have, after mature deliberation, recognized and been led to pronounce their verdict against an act of aggression which in their judgment has been deliberately committed by one of their fellow-members, one of the foremost Powers of Europe; that they should have, for the most part, agreed to impose collectively sanctions on the condemned aggressor, and should have succeeded in carrying out, to a very great measure, their decision, is no doubt an event without parallel in human history. For the first time in the history of humanity the system of collective security, foreshadowed by Bahá’u’lláh and explained by ‘Abdu’l Bahá, has been seriously envisaged, discussed and tested. For the first time in history it has been officially recognized and publicly stated that for this system of collective security to be effectively established strength and elasticity are both essential—strength involving the use of an adequate force to ensure the efficacy of the proposed system, and elasticity to enable the machinery that has been devised to meet the legitimate needs and aspirations of its aggrieved upholders. For the first time in human history tentative efforts have been exerted by the nations of the world to assume collective responsibility, and to supplement their verbal pledges by actual preparation for collective action. And again, for the first time in history, a movement of public opinion has manifested itself in support of the verdict which the leaders and representatives of nations have pronounced, and for securing collective action in pursuance of such a decision.

1936: The League of Nations: - “The voices that have been raised ever since its inception, the efforts that have been exerted, the work that has already been accomplished, foreshadow the triumphs which this presently constituted institution, or any other body that may supersede it, is destined to achieve.”

And yet while the shadows are continually deepening, might we not claim that gleams of hope, flashing intermittently on the international horizon, appear at times to relieve the darkness that encircles humanity? Would it be untrue to maintain that in a world of unsettled faith and disturbed thought, a world of steadily mounting armaments, of unquenchable hatreds and rivalries, the progress, however fitful, of the forces working in harmony with the spirit of the age can already be discerned? Though the great outcry raised by post-war nationalism is growing louder and more insistent every day, the League of Nations is as yet in its embryonic state, and the storm clouds that are gathering may for a time totally eclipse its powers and obliterate its machinery, yet the direction in which the institution itself is operating is most significant. The voices that have been raised ever since its inception, the efforts that have been exerted, the work that has already been accomplished, foreshadow the triumphs which this presently constituted institution, or any other body that may supersede it, is destined to achieve.

1936: “Every system, short of the unification of the human race, has been tried, repeatedly tried, and been found wanting.”; “An ever-deepening gloom is settling on its fortunes as she recedes further and further from the outer fringes of the darkest zone of its agitated life and penetrates its very heart.”

Beset on every side by the cumulative evidences of disintegration, of turmoil and of bankruptcy, serious-minded men and women, in almost every walk of life, are beginning to doubt whether society, as it is now organized, can, through its unaided efforts, extricate itself from the slough into which it is steadily sinking. Every system, short of the unification of the human race, has been tried, repeatedly tried, and been found wanting. Wars again and again have been fought, and conferences without number have met and deliberated. Treaties, pacts and covenants have been painstakingly negotiated, concluded and revised. Systems of government have been patiently tested, have been continually recast and superseded. Economic plans of reconstruction have been carefully devised, and meticulously executed. And yet crisis has succeeded crisis, and the rapidity with which a perilously unstable world is declining has been correspondingly accelerated. A yawning gulf threatens to involve in one common disaster both the satisfied and dissatisfied nations, democracies and dictatorships, capitalists and wage-earners, Europeans and Asiatics, Jew and Gentile, white and colored. An angry Providence, the cynic might well observe, has abandoned a hapless planet to its fate, and fixed irrevocably its doom. Sore-tried and disillusioned, humanity has no doubt lost its orientation, and would seem to have lost as well its faith and hope. It is hovering, unshepherded and visionless, on the brink of disaster. A sense of fatality seems to pervade it. An ever-deepening gloom is settling on its fortunes as she recedes further and further from the outer fringes of the darkest zone of its agitated life and penetrates its very heart.
