The truth is, I was never a very good Party man. Probably but for the War of 1914, I should have gone on fairly comfortably as a Conservative officia… - Robert Cecil

No doubt there is a good deal that is attractive about the nationalist idea. It has a great history and it has a great deal of appeal to sentiment in itself admirable. But if we examine what it leads to, I do not doubt that we shall all agree that it must be rejected as a guiding principle of the nations of the world. For it necessarily leads to an exaggeration of the authority and dignity of the state to an extent which practically destroys individual action and individual responsibility. Nationalism leads to totalitarianism, and totalitarianism leads to idolatry. It becomes not a principle of politics but a new religion and, let me add, a false religion. It depends partly on a pseudoscientific doctrine of race which leads inevitably to the antithesis of all that we value in Christian morality. On the other hand, if we accept the view that all nations are interdependent, as individuals in any society are, we get precisely the opposite result. Such a principle leads to friendliness and good neighbourhood and, indeed, it is not too much to say that it leads to everything that we have hitherto understood as progress and civilization.

I was brought up from my earliest youth to believe in the enormous importance of peace. I have often heard my father, the late Lord Salisbury, say that, though he did not see how it was possible under the then existing circumstances to avoid wars altogether, yet he had never been able to satisfy himself that they were in principle morally defensible.
Indeed, particularly in the latter part of his life, he made more than one speech in which he expressed the hope that, by some international combination, wars could in the future be prevented. He did not hesitate to express his belief that some such organization as we have since then attempted and erected in the League of Nations might furnish the solution of what he conceived to be the terrific evil of war.

In 1932 when the Disarmament Conference, after many years of preparation, at last assembled, it really looked as if we were approaching something like stabilized conditions in the world. I am still convinced that with a little more courage and foresight, particularly among those who were directing the policy of the so-called Great Powers, we might have achieved a limitation of international armaments, with all the enormously beneficial consequences which that would have given us. … No doubt the work has not succeeded; but I like to believe that it has not been altogether lost. We have laid a foundation on which, ultimately, we may build something in the nature of reform. And I am perfectly satisfied that the attempt to limit and reduce armaments by international action must be resumed and the sooner the better, if the world is to be saved from a fresh and bloody disaster.
