Iran has not allowed the IAEA to visit a site at the Parchin military complex or other sites associated with past work on nuclear weapons research and development and other military nuclear activities. · Iran has delayed inspectors’ access to sites and extensively modified buildings or the sites themselves in apparent efforts to thwart IAEA verification methods which aim to detect undeclared activities and facilities. Iran attempted to prevent these methods from succeeding in 2003 at the Kalaye Electric centrifuge research and development site but was caught; its efforts at sanitization and concealment succeeded at the Lavisan-Shian site, which it bulldozed and rebuilt into an athletic facility after suspicion was raised that it was allegedly involved in military nuclear work; Iran’s efforts may yet succeed to conceal from environmental sampling and other verification techniques any past work at the Parchin site where high explosive tests related to nuclear weaponization may have been conducted. · Iran has stonewalled the IAEA’s efforts to resolve its concerns about the possible military dimensions of its nuclear programs.

There is no historical Iran nuclear agreement; it’s a bag of empty promises
