For if Reza Shah’s initial model was Atatürk, by the 1930s he had become entranced by Europe’s Fascists. In his quest to find a source of investment capital and expertise independent of the British and Russians, Reza Shah opened Iran to the Germans, who flooded into the country in some numbers. The British and Soviets combined to insist that Reza Shah expel them so as to protect supply routes to the desperate Soviets, and, although he complied, they occupied his country anyway and he went into exile. The Allies put his twenty-one-year-old son Mohammed Reza Shah on the throne, in events witnessed by the young Ayatollah Ruhollah Khomenei. Mohammed was a soft pastiche of Daddy.

A British consular official, Sir Claremont Skrine, was based throughout the war in Meshed, a city within the increasingly closed Soviet north of Iran. His main task was to expedite transhipments of war materials going to the Soviet Union. In his peripheral vision Skrine also noted another power in the land, the third party to a tripartite treaty which guaranteed Iran’s sovereignty and territorial integrity, with a supplemental promise to evacuate the country six months after the cessation of global hostilities. Thirty thousand US troops radically increased the carrying capacity of the Trans-Iranian Railway bearing Lend-Lease materials northwards. The fiscal expert Arthur Millspaugh returned to run Iran’s public finances. Colonel H. Norman Schwarzkopf, the founder of the New Jersey State Police, was imported to reorganize the Iranian paramilitary Gendarmerie. He was to return in 1953 as part of a joint CIA–SIS operation to overthrow Mossadeq and reinstate the Shah.

Astonishing the number of lines that cross through history. Colonel H. Norman Schwarzkopf is, of course, the father of General Norman Schwarzkopf of Gulf War I fame. Schwartzkopf Sr. was also, as chief of New Jersey State Police, deeply involved in the Lindbergh Baby Kidnapping case.

The other thing that passage serves to remind us of is just how far our troops were deployed in WWII. Of course the European Theater and the Pacific. But who thinks of Burma, India, Iran, Iceland, Brazil, China, Peru, Saudi Arabia, etc.
