It is obvious that there are many difficulties of detail in its application; that a plébiscite may be a mere form and not reflect the real wishes of the population concerned, and under military control it can be used as an instrument for obtaining an apparent sanction for oppression, and that in populations of mixed race it is very difficult of application. But it should not be impossible to guard against the defeat of the principle through defects in the working machinery. Plébiscites, where used at the end of the war, might be carried out under international supervision. The essential is that the principle involved should be clearly enunciated. Fortunately the Government has already given the country a valuable lead in this matter. For Mr. Churchill, speaking on September 11, said: “Now the war has come, and when it is over let us be careful not to make the same mistake or the same sort of mistake as Germany made when she had France prostrate at her feet in 1870. [Cheers.] Let us, whatever we do, fight for and work towards great and sound principles for the European system, and the first of those principles which we should keep before us is the principle of nationality—that is to say, not the conquest or subjugation of any great community, or of any strong race of men, but the setting free of those races which have been subjugated and conquered; and if doubt arises about disputed areas of country we should try to settle their ultimate destination in the reconstruction of Europe which must follow from this war with a fair regard to the wishes and feelings of the people who live in them.” [Sidenote: One nation must not be allowed to dominate another.] We agree with Mr. Churchill that the terms of peace should secure that there shall in the future be no more Alsace-Lorraines to create during half a century resentment, unrest, and intrigues for a _revanche_. The power of the victorious parties must not be used for vindictive oppression and dismemberment of beaten nationalities, but for the creation, by cooperation with all the belligerents, victors and vanquished alike, of a true society of nations, banded together for mutual security. The future relationship of the States of Europe must be not that of victor and vanquished, domination or subserviency, but of partnership. The struggle of one nation for domination over another must be replaced by the association of the people for their common good. II _No Treaty, Arrangement, or Undertaking shall be entered upon in the name of Great Britain without the sanction of Parliament. Adequate machinery for ensuring democratic control of foreign policy shall be created._ [Sidenote: Secret diplomacy must go.]
