The Indian states and the new Constitution

Ben Affleck's film ARGO is a good film, but not all the details are accurate. This article is by Martin Williams, the British diplomat who, contrary to the picture painted in the film, personally escorted to safety the Americans who had escaped when the Iranian Revolutionary guards took over the US Embassy. He sets that episode in the broader context of his personal experience of working during a complicated period during which initially there were major commercial opportunities for British firms, and then the power of the Shah started to wane, and finally he was overthrown. The installation of a very different regime entirely changed the approach which diplomats needed to adopt in Tehran.
