It is not insurrection we now want in Italy, or elsewhere—we want disciplined force, under Sovereigns we can trust. - Robert Stewart, Viscount Castlereagh

In thus attempting to limit the objects of the Alliance within their legitimate Boundary, it is not meant to discourage the utmost frankness of communication between the Allied Cabinets; their Confidential Intercourse upon all Matters, however foreign to the Purposes of the Alliance, is in itself a valuable expedient for keeping the current of sentiment in Europe as equable and as uniform as may be... but what is intended to be combated as forming any part of their Duty as Allies, is the Notion, but too perceptibly prevalent, that whenever any great Political Event shall occur, as in Spain, pregnant perhaps with future Danger, it is to be regarded almost as a matter of course, that it belongs to the Allies to charge themselves collectively with the Responsibility of exercising some Jurisdiction concerning such possible eventual Danger. One objection to this view of our Duties, if there was no other, is, that unless We are prepared to support out interference with force, our judgment or advice is likely to be but rarely listened to, and would by frequent Repetition soon fall into complete contempt. So long as We keep to the great and simple conservative principles of the Alliance, when the Dangers therein contemplated shall be visibly realised, there is little risk of difference or of disunion amongst the Allies.

These arguments about natural defences and strategic boundaries are pushed too far. Real defence and security comes from the guarantee which is given by the fact that they cannot touch you without declaring war on all those interested in maintaining things as they are.

It is impossible not to feel the appeal; and if a statesman were permitted to regulate his conduct by the counsels of his heart instead of the dictates of his understanding, I really see no limits to the impulse, which might be given to his conduct, upon a case so stated. But we must always recollect that his is the grave task of providing for the peace and security of those interests immediately committed to his care; that he must not endanger the fate of the present generation in a speculative endeavour to improve the lot of that which is to come.
