As opposed to France, a peace concluded in concert, though less advantageous in its terms, would be preferable to the largest concessions received fr… - Robert Stewart, Viscount Castlereagh

The system of the Emperor [of Russia] did him honour as a monarch and as a man. Nothing could be more pure than the ends which he had set before himself in all his actions; but this system aims at a perfection, which we do not believe applicable to this century or to mankind. We cannot follow him along this path. It is a vain hope, a beautiful phantom, which England above all can not pursue. All speculative policy is outside her powers. It is proposed now to overcome the revolution; but so long as this revolution does not appear in more distinct shape, so long as this general principle is only translated into events like those of Spain, Naples and Portugal—which, strictly speaking, are only reforms, or at the most domestic upsets, and do not attack materially any other State—England is not ready to combat it. Upon any other question purely political, she would always deliberate and act in the same way as all the other Cabinets.

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.

If we are to undertake the job, we must leave nothing to chance. It must be done upon the largest scale... [Y]ou must inundate France with force in all directions. If Bonaparte could turn the tide, there is no calculating upon his plan; and we must always recollect that Poland, Saxony, and much Jacobinism, are in our rear.
