Israel maintains a doctrine of "nuclear ambiguity" and has never confirmed nor denied having its own nuclear weapons program. It considers Iran a serious threat not only because of Tehran's nuclear program but also because of Iran's arsenal of long-range missiles, which can be fitted with nuclear warheads and are capable of striking the Jewish state.
Iran's missile program and its nuclear work — much of it carried out in secrecy — have long been a concern for the West, which fears Tehran is intent on developing an atomic weapons capability and the missiles to deploy such warheads.
Why do you have to use "Ambiguity" for Israel and "Secrecy" for Iranian programs? Then why should only West right to have had "a concern" about Iran and no mention of Iran's right to be concern about "Ambiguity" of Israel nuclear missiles? If the concern is to talk about the tension shouldn't one need to address the both side of it?
