To meet the extraordinarily ambitious targets of the first Five Year Plan, Soviet factories urgently required machines, parts, tools and other things available only for hard currency. In a letter to Molotov in July 1930, Stalin was already writing of the need to “force the export of grain…this is the key.” In August, fearing that American grain would soon flood the market, he again urged speed: “if we don’t export 130–150 million poods [2.1–2.4 million tonnes] our currency situation may become desperate. Once again: we must force the export of grain with all of our strength.”
