Vierjahresplan
Overy argued that there was a difference between economic pressures induced by the problems of the Four Year Plan and economic motives to seize raw materials, industry and foreign reserves of neighbouring states as a way of accelerating the Four Year Plan. Overy asserted that the repressive capacity of the German state as a way of dealing with domestic unhappiness was somewhat downplayed by Mason. Finally, Overy argued that there is considerable evidence that Germany felt that it could master the economic problems of rearmament; as one civil servant put it in January 1940, "we have already mastered so many difficulties in the past, that here too, if one or other raw material became extremely scarce, ways and means will always yet be found to get out of a fix".
