Leader of the opposition in the Knesset, Zionist Union MK Issac Herzog, called US Secretary of State John Kerry a 'great friend' who has shown 'true concern' about Israel's future shortly after America's chief diplomat delivered a speech in Washington. 'John Kerry has always been a great friend of Israel and will always be. His speech expresses true concerns about Israels well-being & future,' Herzog wrote in a tweet.
