When this commission assembled, one of its members, Lord Esher, suggested fixing a unity of comparison for land forces, such as the Washington Conference had done for naval armaments. The committee considered that armies are not the same thing as fleets, nor are military effectives like warships : that the number of soldiers is not the only factor to consider in the military strength of nations. This latter could not be expressed by a mathematical formula which took no account of either economic power, or of industrial resources. The commission pointed out that by reason of the character of war between armed nations, each nation possessed, behind the visible front of its peace time armaments, potential war-waging capacity. These conclusions were submitted to the League of Nations Assembly which, in its 1921 session, proposed that its Council should proceed to an enquiry into the armaments of the different countries since 1913; it demanded precise details about the different war budgets, about the requirements of national security in every country, about its international obligations. Thus, by degrees, the complexity of the disarmament problem appeared. Lord Robert Cecil therefore, in the Temporary Commission itself, proposed to solve the problem in a very general way, by offering to all the Governments guaran tees for the security of their countries, in return for their firm undertaking to reduce armaments. On the other hand, the Per manent Advisory Commission declared that all the guarantees would be inefficacious, unless a plan of defence were previously drawn up; and from that very point arose the question how can it be determined from which side comes the aggression. The mecha nism of the mutual guarantee was in itself a subject of discussion.
While Lord Robert Cecil contented himself with a general under taking, the French delegate, M. de Jouvenel, showed more confi dence in private treaties. It is a long time ago since Lord Chan cellor Bacon said "a mean must be observed in every doctrine, and science, and in the rules and axioms thereof, between the rocks of distinctions and the whirlpools of universalities." The third Assembly of the League of Nations (1922) adopted a celebrated resolution which is known by the name of "resolu tion XIV." and which, although trying to conciliate the themes under discussion, adopted, for the most part, the proposals of Lord Robert Cecil. It acknowledged that in the actual state of the world it was impossible for a great number of Governments to proceed to a serious reduction of armaments, if they had not sufficient guarantees for the security of their countries. These guarantees could be furnished by a defensive agreement open to all countries and resting upon a plan for defence preyiously drawn up. The Council of the League was to establish and submit to the different Governments the plan of political and military mecha nism calculated to realize and assure this resolution.
