I agree with the prime minister that the condition of the world is serious, and that everyone who speaks on these subjects must speak with a full sense of responsibility, but that does not mean, in my view, that there should be a lack of plain speaking, but that we ought to see the facts for what they really are. I must say that I was profoundly disappointed with the speech of the prime minister, because it seemed to me that he had misconceived the whole issue that lives before us. He suggested that there was being fought in Spain, in the opinion of some people, a struggle between two sides, two rival systems. I do not think that is the issue that is facing us to-day. The world to-day is faced with a contest between two sides, and those two sides are whether the rule of law in international affairs shall prevail, or the rule of lawless force. That is the issue that faces us, and we must look at this Spanish struggle in its true perspective.
