Israeli media are reporting that a small and unconventional Iran office in the Israeli Ministry of Defense will be shut down. The 30-year-old office has been headed by 83-year-old Uri Lubrani, who was de facto Israeli ambassador to Iran in the 1970s and famously predicted the fall of the shah. While the closure of the office may seem a minor bureaucratic matter, it also speaks to the demise of an idea that gained currency in some Washington circles just a few years ago and then faded: that the United States might support a plan of regime change in Iran.
