It is also necessary to emphasise the fact that the means which the States signatories to the present Protocol have at their disposal for the fulfilment of the obligations arising out of Article 11 vary considerably owing to the differences in the geographical, economic, financial, political and social condition of different States. Information as to the means at the disposal of each State is therefore indispensable in order that the Council may in full understanding give its opinion as to the best method by which such obligations may best be carried out. Finally, as regards the question of the reduction of armaments, which is the final goal to which our efforts are tending, the information thus furnished to the Council may be of very great importance, as every State, knowing what forces will be available for its assistance in case it is attacked, will be able to judge to what extent it may reduce its armaments without compromising its existence as a State, and every State will thus be able to provide the International Conference for the Reduction of Armaments with very valuable data. I should add, moreover, that Article 13, paragraph 1, does not render it compulsory for States to furnish this information. It is desirable that States should furnish the Council with this information, but they are at liberty not to do so. _Article 13, paragraphs 2 and 3._ The provisions of Article 13, paragraphs 2 and 3, refer to the special agreements which were discussed at such length last year. In view of the fact that, according to paragraph 2, such agreements can only come into force when the Council has invited the signatory States to apply the sanctions, the nature of these agreements may be defined as follows: Special agreements must be regarded as the means for the rapid application of sanctions of every kind in a particular case {205} of aggression. They are additional guarantees which give weaker States an absolute assurance that the system of sanctions will never fail. They guarantee that there will always be States prepared immediately to carry out the obligations provided for in Article 11 of the Protocol. In accordance with Article 18 of the Covenant, it is expressly stated that these agreements will be registered and published by the Secretariat, and it has also been decided that they will remain open for signature to any State Member of the League of Nations which may desire to accede to them. 4.--ENDING OF SANCTIONS: PUNISHMENT OF THE AGGRESSOR. _Article 14._
