The six years of World II and the magnitude of the military operations which were carried out in Africa, in Europe, in Asia, and in the Pacific areas stand as indisputable evidence that the economic strength and the industrial capacity of a nation are decisive factors in the conduct of any major war. It is upon this economic and industrial strength that the armed forces in the field are dependent for their equipment and support.
