Old, I know, but former IAEA DDG for Safeguards Bruno Pellaud made these comments in a 2013 interview about Israel’s nuclear weapons:
Their own bomb provides them with a sort of immunity and in reality, for them, Iran is a danger not only because of the risk of a bomb, but because of its influence over neighbouring states – over Hezbollah, Syria and Lebanon. Israel is behaving in flagrant bad faith. When I was in Vienna, every three months I had a visit from their ambassador who told me: “The Iranians are three months away from having the bomb”. That went on for six years. And now Israeli prime minister Benjamin Netanyahu is continuing to exaggerate, but there is no value to it
