Continuing with David Talbot's The Devil's Chessboard.This part of the narrative finds the clowns in Iran and Guatemala...

[.... Dulles’s arrival in Rome was conveniently timed. By the following morning, the mobs running riot through the streets of Tehran were led and financed by the CIA—the final act in a covert drama aimed at overthrowing the democratically elected government of Prime Minister Mohammad Mossadegh and restoring the shah’s autocratic rule. Mossadegh, a dedicated patriot and wily survivor of Iran’s treacherous politics, had antagonized the British government by nationalizing the powerful Anglo-Iranian Oil Company (later renamed British Petroleum) soon after taking office in 1951. The British behemoth—the third-largest producer of crude oil in the world—ruled Iran with imperial arrogance for much of the twentieth century, crushing labor strikes in the hellish oil fields and propping up and replacing local regimes at will. Mossadegh’s defiant seizure of Iran’s oil treasure set off a global thunderclap. “By the end of the 1980s, most countries in the Middle East and North Africa, as well as Asia and Latin America, had nationalized their oil, and thus gained influence over world prices,” observed historian Ervand Abrahamian. “In the early 1950s, however, such a loss was seen as heralding the ‘end of civilization’—not only for Britain but also for consumers throughout the industrial world.”

After Mossadegh’s bold move, the British spy agency MI6 began working strenuously to undermine his government. When the prime minister responded to the British plotting by shutting down the British embassy in Tehran and ejecting the ambassador, London turned to Washington for assistance.

The Dulles's were more than willing to help. Through their law firm, the brothers had long ties to major U.S. oil companies like Standard Oil, which strongly supported the tough British stand against Mossadegh, with hopes of securing their own stake in the Iranian oil fields. Allen had another former client with a big interest in the Iranian oil dispute: the London-based J. Henry Schroder Banking Corporation, on whose board he served, was the financial agent for Anglo-Iranian Oil.

The Dulles brothers had demonstrated their dedication to their former Sullivan and Cromwell petroleum clients soon after President Eisenhower took office by sabotaging a Justice Department antitrust case against the Seven Sisters oil giants. The price-fixing case against the oil cartel, a holdover from the Truman years, was reduced from a criminal to a civil charge and conveniently transferred to Foster Dulles’s jurisdiction, the first time in U.S. history that an antitrust case was handed over to the State Department for prosecution. Foster argued that the case had national security implications, and it quietly disappeared, leaving Big Oil unscathed.

Furthermore, Allen Dulles had a business history with the shah. In 1949, while still employed as a Sullivan and Cromwell rainmaker, Dulles had flown to Tehran, where he met the shah and negotiated a stunningly lucrative deal on behalf of a new company called Overseas Consultants Inc., a consortium of eleven large U.S. engineering firms. Iran agreed to pay OCI a Croesus-like fortune of $650 million for which the consortium pledged to modernize the backward nation, building hydroelectric plants, importing industries, and transforming entire cities. “This would be the largest overseas development project in modern history,” noted Dulles biographer Stephen Kinzer. “It was the greatest triumph of Allen’s legal career. For Sullivan and Cromwell it opened a world of possibilities.”
