“As the producer states gradually forced the major oil companies to share with them more of the profits from oil, increasing quantities of sterling and dollars flowed to the Middle East. To maintain the balance of payments and the viability of the international financial system, Britain and the United States needed a mechanism for these currency flows to be returned. [...]

The purchase of most goods, whether consumable materials like food and clothing or more durable items such as cars or industrial machinery, sooner or later reaches a limit where, in practical terms, no more of the commodity can be used and further acquisition is impossible to justify. Given the enormous size of oil revenues, and the relatively small populations and widespread poverty of many of the countries beginning to accumulate them, ordinary goods could not be purchased at a rate that would go far to balance the flow of dollars (and many could be bought from third countries, like Germany and Japan – purchases that would not improve the dollar problem). Weapons, on the other hand, could be purchased to be stored up rather than used, and came with their own forms of justification. Under the appropriate doctrines of security, ever-larger acquisitions could be rationalised on the grounds that they would make the need to use them less likely. Certain weapons, such as US fighter aircraft, were becoming so technically complex by the 1960s that a single item might cost over $10 million, offering a particularly compact vehicle for recycling dollars. Arms, therefore, could be purchased in quantities unlimited by any practical need or capacity to consume. As petrodollars flowed increasingly to the Middle East, the sale of expensive weaponry provided a unique apparatus for recycling those dollars – one that could expand without any normal commercial constraint.”
