That necessary international co-operation had, as a matter of fact, been largely developed before the War. The cheapening of transport, the improvement of communication, had pushed the international division of labour very far indeed. The material in a single bale of clothes would travel half round the world several times, and receive the labour of half a dozen nationalities, before finally reaching its consumer. But there was this very significant fact about the whole process; Governments had very little to do with it, and the process did not rest upon any clearly defined body of commercial right, defined in a regular code or law. One of the greatest of all British industries, cotton spinning, depended upon access to raw material under the complete control of a foreign State, America. (The blockade of the South in the War of Secession proved how absolute was the dependence of a main British industry upon the political decisions of a foreign Government). The mass of contradictory uncertainties relating to rights of neutral trade in war-time, known as International Law, furnished no basis of security at all. It did not even pretend to touch the source--the right of access to the material itself. That right, and the international economy that had become so indispensable to the maintenance of so much of the population of Western Europe, rested upon the expectation that the private owner of raw materials--the grower of wheat or cotton, or the owner of iron ore or coal-mines--would continue to desire to sell those things, would always, indeed, be compelled so to do, in order to turn them to account. The main aim of the Industrial Era was markets--to sell things. One heard of 'economic invasions' before the War. This did not mean that the invader took things, but that he brought them--for sale. The modern industrial nation did not fear the loss of commodities. What it feared was their receipt. And the aid of Governments was mainly invoked, not for the purpose of preventing things leaving the country, but for the purpose of putting obstacles in the way of foreigners bringing commodities into the country. Nearly every country had 'Protection' against foreign goods. Very rarely did we find countries fearing to lose their goods and putting on export duties. Incidentally such duties are forbidden by the American Constitution. Before the War it would have seemed a work of supererogation to frame international regulations to protect the right to buy: all were searching for buyers. In an economic world which revolved on the expectation of individual profit, the competition for profit kept open the resources of the world.
