With open lands for collateral already in short supply, the US Government embarked on a new program to shore up sagging international demand for the dollar. The United States approached the world’s oil producing nations, mostly in the Middle East, and offered them a deal. In exchange for only selling their oil for dollars, the United States would guarantee the military safety of those oil-rich nations. The oil rich nations would agree to spend and invest their US paper dollars inside the United States, in particular in US Treasury Bonds, redeemable through the slave labor of future generations of US taxpayers. The concept was labeled the “petrodollar”. In effect, the US, no longer able to back the dollar with gold, was now backing it with oil. Other peoples’ oil. And that necessity to keep control over those oil nations to prop up the dollar has shaped America’s foreign policy in the region ever since.
