JERUSALEM (CNN) -- Israel makes no secret that it sees Iran is its biggest threat but the scale of the threat is less clear cut. Israel's recent military exercises are seen by some as a show of strength to Iran. Prime Minister Benjamin Netanyahu has not missed an opportunity to name Iran as the number one threat, and like his predecessors he has said Israel will not tolerate a nuclear Iran. Tests are ongoing for Israel's arrow missile system, designed to intercept incoming rockets -- although Israel does not openly say which direction they'd come from. Last week, CNN filmed Netanyahu aboard an F15 fighter-bomber jet while touring the Hatzerim air force base near Beersheva. He said: "My biggest impression today is the obligation to carry out the mission of defending Israel."
