But the attempt at such coercion, the inevitable results of a policy aimed at securing predominant power, provoking resistance and friction, can and does paralyse the necessary processes, and by so doing is undermining the economic foundations of British life. What are the facts supporting the foregoing proposition? Many whose instincts of national protection would become immediately alert at the possibility of a naval blockade of these islands, remain indifferent to the possibility of a blockade arising in another but every bit as effective a fashion. That is through the failure of the food and raw material, upon which our populations and our industries depend, to be produced at all owing to the progressive social disintegration which seems to be going on over the greater part of the world. To the degree to which it is true to say that Britain's life is dependent upon her fleet, it is true to say that it is dependent upon the production by foreigners of a surplus above their own needs of food and raw material. This is the most fundamental fact in the economic situation of Britain: a large portion of her population are fed by the exchange of coal, or services and manufactures based on coal, for the surplus production, mainly food and raw material, of peoples living overseas.[2] Whether the failure of food to reach us were due to the sinking of our ships at sea or the failure of those ships to obtain cargoes at the port of embarkation the result in the end would be the same. Indeed, the latter method, if complete, would be the more serious as an armistice or surrender would not bring relief.
