US Ambassador to Israel Jack Lew referred on Thursday at the Institute for National Security Studies (INSS) conference to President Joe Biden's criticism of Prime Minister Benjamin Netanyahu, when he said that he was not doing enough to promote a deal. "He was asked a question, and gave a one-word answer - 'no.' I would not attach too much meaning to one word. Everyone needs to do more," he said. According to Lew, despite the public confrontation, decisions continue to be made. "The negotiations go into the most difficult issues, some of them are not the ones that stand out in the public discussion," he added.
