The connection between public opinion and public policy is slighter in foreign affairs than in any other sphere of politics. In normal times, international relations have little palpable impact upon the life of the people, and are obscured by more vivid domestic issues until war or some sudden crisis throws a high light on their significance. Even since the Great War, although public realization of the importance of foreign affairs has begun to be aroused in the late belligerent countries—in England at any rate—direct contact between popular opinion and government action is still both sporadic and uncertain.

What is true of the British nation is almost equally true of its representative assembly. Parliament has but little power over foreign affairs. Some of the most momentous changes in the country's relations with other Powers have, in the present century, been accomplished without reference to the House of Commons, and often without even its knowledge. Like the people themselves, the people's representatives exercise only an inconsiderable control over that branch of public affairs which is at present of more vital concern than any other.

Most British foreign secretaries, indeed, regard their actions as matters of exclusively executive concern. A cabinet of twenty ministers, already overworked in their own departments, is not, however, a body which can conduct the country's foreign relations. On his own subject, the Foreign Secretary dominates his ministerial colleagues. Experience shows that he can avoid consultation with all the cabinet save two or three of the principal ministers.
