JERUSALEM (Reuters) -Iran once ridiculed Israeli Prime Minister Benjamin Netanyahu as the boy who cried wolf for his constant public warnings about Tehran's nuclear programme, and his repeated threats to shut it down, one way or another. "You can only fool some of the people so many times," Iran's then-foreign minister, Mohammad Javad Zarif, said in 2018 after Netanyahu had once again accused Iran of planning to build nuclear weapons. On Friday, after two decades of continually raising the alarm and urging other world leaders to act, Netanyahu finally decided to go it alone, authorising an Israeli air assault aimed, Israel says, at preventing Iran from obtaining weapons of mass destruction.
