prevent the diversion of advanced technology to the Soviet bloc and China and, in later years, to alter the behavior of foreign countries. Scarcity of certain goods in the world markets made the continuance of controls necessary to prevent a drain on such goods from plentiful American supplies, with its consequential inflationary influence. It was envisioned that remaining controls would soon disappear at the time of re-enactment in 1949, but national security and foreign policy, especially following the outbreak of the Korean War, were new and compelling reasons for extending the Export Control Act of 1949 in 1951, 1953, 1956 and again in 1958. The Export Control Act of 1949 is an example of the type of legislation that it renders, subject to the regulations promulgated under it, all persons wherever situated. Under its provisions, exports of scarce materials are controlled both from an economic standpoint (short supply and consequent inflationary effect on foreign demand) and the security standpoint (autarchy and self-sufficiency in strategic resources not available in sufficiently-large quantities). They are both domestic policies aimed primarily at conditions within the United States, but controls are also directed at conditions outside the country as an instrument of US foreign policy. That is exemplified by the restrictions on the export of certain strategic or military items to the Soviet bloc or to other countries that it felt, if permitted, would be detrimental to American foreign policy. The last motive became so strong that it brought legislation directing the president to enlist the co-operation of other nations in enacting controls on trade with the Soviet block to parallel those of the United States. The benefits of the various economic and military aid programs were to be withheld from non-cooperating nations.
