✔ 最佳答案
The most important effect of the war is the set up of Organization of Petroleum Exporting Countries, or OPEC.
With OPEC, the control of oil supply was not in the hand of USA any more. OPEC controlled the supply of oil and had oligopolistic power on oil price. The high oil price had crippled many industries of the Western countries and badly affected their economy.
Wealth of the earth was transferred to the Arab states and it saw the rapid depreciation of US dollar, causing high interest rates and further hardship to US economy in the early 80's.
The oil money eventually found its way back to USA and the West in the form of investment and capital consumption by the rich oil producing countries.
