President Isaac Herzog told the World Economic Forum conference in Davos, Switzerland: "I warn the world not to fall into optimism. Yes, there is a great opportunity to change the course of the Middle East for the better, but there is a great danger as long as the regime in Iran remains in place." Herzog referred to Israel-Saudi relations and said: "There is a real dialogue between Israel and Saudi Arabia. Saudi Arabia is a very important country in the region. I believe that we need to promote this."
