US President Donald Trump briefly laid out his rationale for a possible attack on Iran in his State of the Union address to Congress, saying he would not allow it to obtain a nuclear weapon. Here are some questions and answers about his statements: What specifically did Trump say about Iran’s weapons programs? Trump said that Iran has developed missiles that could threaten Europe and American bases abroad, and that it is “working to develop missiles that will soon reach the United States of America.” He added that the US air strikes he ordered in June “eliminated” Iran’s nuclear weapons program, but Tehran was “starting over” and “at this moment is seeking again to achieve its evil ambitions.”
