Wow...I never knew that. I heard the German story in school & Wikipedia. The need updating...
There are cyberbullies and web brigades of the islamic regime, plus assorted iranian and western leftists who removed all my (and other) changes and injected their bias everywhere.
Since some months I observed that someone (probably regime agents) is simply removing Pahlavi history from Iran related articles, as if it never happened. There are articles (for example on women's rights) where half a century of progress under the Pahlavi's simply doesn't exist. It's 19th century... and blammo! Islamic Revolution 1979.
Maybe when I find some time, I'll try it again. *sigh*
If you are interested, there are three excellent books on Iranian history 1921-41 I'd recommend:
Yair P. Hirschfeld, Iran und Deutschland 1921-1941 (Israeli author, but the book is only in German. This is an excellently sourced book on German-Iranian relations and debunks thoroughly the "Shah was pro-Nazi" propaganda.)
Richard Stewart, Sunrise at Abadan (an US Marine officer and historian has meticulously researched the circumstances of the Anglo-Soviet Invasion of Iran. It's a military history primarily, but a very good read.)
Donald Wilber, Riza Shah (from the 1970's but still the best biography of Reza Shah. Some facts have been updated by more recent research, but Wilber talked to many primary sources and witnesses, and the book is enjoyable and has information that was neglected by other works.)
