I agree that, if either Government had grave reason to expect an unprovoked attack by a third Power, or something that threatened the general peace, it should immediately discuss with the other whether both Governments should act together to prevent aggression and to preserve peace, and, if so, what measures they would be prepared to take in common. If these measures involved action, the plans of the General Staffs would at once be taken into consideration, and the Governments would then decide what effect should be given to them. Yours, &c. E. GREY. No. 119. _Sir Edward Grey to Sir F. Bertie_. Sir, _Foreign Office, July_ 31, 1914. M. Cambon referred to-day to a telegram that had been shown to Sir Arthur Nicolson this morning from the French Ambassador in Berlin, saying that it was the uncertainty with regard to whether we would intervene which was the encouraging element in Berlin, and that, it we would only declare definitely on the side of Russia and France, it would decide the German attitude in favour of peace. I said that it was quite wrong to suppose that we had left Germany under the impression that we would not intervene. I had refused overtures to promise that we should remain neutral. I had not only definitely declined to say that we would remain neutral, I had even gone so far this morning as to say to the German Ambassador that, if France and Germany became involved in war, we should be drawn into it. That, of course, was not the same thing as taking an engagement to France, and I told M. Cambon of it only to show that we had not left Germany under the impression that we would stand aside. M. Cambon then asked me for my reply to what he had said yesterday. I said that we had come to the conclusion, in the Cabinet to-day, that we could not give any pledge at the present time. Though we should have to put our policy before Parliament, we could not pledge Parliament in advance. Up to the present moment, we did not feel, and public opinion did not feel, that any treaties or obligations of this country were involved. Further developments might alter this situation and cause the Government and Parliament to take the view that intervention was justified. The preservation of the neutrality of Belgium might be, I would not say a decisive, but an important factor, in determining our attitude. Whether we proposed to Parliament to intervene or not to intervene in a war, Parliament would wish to know how we stood with regard to the neutrality of Belgium, and it might be that I should ask both France and Germany whether each was prepared to undertake an engagement that she would not be the first to violate the neutrality of Belgium. M. Cambon repeated his question whether we would help France if Germany made an attack on her. I said that I could only adhere to the answer that, as far as things had gone at present, we could not take any engagement.
