Twin Pillars Policy


U.S. policy to promote Iran and Saudi Arabia as local guardians of U.S. interests in the Persian Gulf region.

The decision by Great Britain in the late 1960s to withdraw its military forces from the Persian Gulf and to grant independence to its ten protectorates along the east coast of the Arabian Peninsula confronted the United States with a strategic dilemma. It was the height of Cold War rivalry with the Soviet Union, and the United States was deeply involved in Vietnam. Consequently, the United States decided instead of direct intervention to build up its two regional allies, Iran and Saudi Arabia, as local powers that could protect the region from the spread of Soviet influence. As the "twin pillars" of U.S. policy, both countries were encouraged to acquire billions of dollars of the most advanced arms during the 1970s. Iran embraced the twin pillars policy more enthusiastically than Saudi Arabia and intervened militarily, with U.S. approbation, in Iraq and Oman. The policy collapsed suddenly in 1979, when the shah (king) of Iran was overthrown in a revolution that brought to power a republican regime opposed to U.S. influence in the region.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
