EG is correct about the machinations of the U.S. in Persia. Reza Pahlavi was installed in 1953, to replace Mohammed Mossadeq (sp?). I've found a rather good page for this, and i see nothing i consider a glaring distortion of the historical record. If you are sceptical about the source, at the bottom of the page is an "about us" link and a "disclaimer" link, and you can decide for yourself what you believe. Whatever you decide about what to believe, it is indisputable that the U.S. overthrew Mossadeq in favor of Pahlavi, described in this article as someone despised by the CIA.
A short account of the 1953 coup
(For those used to fast, fast on line relief, i would note that for historians, three pages is a short account indeed.)
