There is, I admit, the obligation of the treaty.  It is not necessary, nor would time permit me, to enter into the complicated question of the nature of the obligations of that treaty; but I am not able to subscribe to the doctrine of those who have held in this House what plainly amounts to an assertion, that the simple fact of the existence of a guarantee is binding on every party to it, irrespectively altogether of the particular position in which it may find itself at the time when the occasion for acting on the guarantee arises.  The great authorities upon foreign policy to whom I have been accustomed to listen, such as Lord Aberdeen and Lord Palmerston, never to my knowledge took that rigid and, if I may venture to say so, that impracticable view of the guarantee.  The circumstance that there is already an existing guarantee in force is of necessity an important fact, and a weighty element in the case to which we are bound to give full and ample consideration.  There is also this further consideration, the force of which we must all feel most deeply, and that is, the common interests against the unmeasured aggrandizement of any Power whatever.

The treaty is an old treaty—­1839—­and that was the view taken of it in 1870.  It is one of those treaties which are founded, not only on consideration for Belgium, which benefits under the treaty, but in the interests of those who guarantee the neutrality of Belgium.  The honour and interests are, at least, as strong to-day as in 1870, and we cannot take a more narrow view or a lass serious view of our obligations, and of the importance of those obligations than was taken by Mr. Gladstone’s Government in 1870.

I will read to the House what took place last week on this subject.  When mobilization was beginning, I knew that this question must be a most important element in our policy—­a most important subject for the House of Commons.  I telegraphed at the same time in similar terms to both Paris and Berlin to say that it was essential for us to know whether the French and German Governments respectively were prepared to undertake an engagement to respect the neutrality of Belgium.  These are the replies.  I got from the French Government this reply: 

The French Government are resolved to respect the neutrality of Belgium, and it would only be in the event of some other Power violating that neutrality that France might find herself under the necessity, in order to assure the defence of her security, to act otherwise.  This assurance has been given several times.  The President of the Republic spoke of it to the King of the Belgians, and the French Minister at Brussels has spontaneously renewed the assurance to the Belgian Minister of Foreign Affairs to-day.

From the German Government the reply was: 

  The Secretary of State for Foreign Affairs could not
  possibly give an answer before consulting the Emperor and
  the Imperial Chancellor.
