Will Iran’s missile attack deter Israeli military action in Lebanon?

Iran launched a retaliatory missile barrage against Israeli military infrastructure on Tuesday in response to Israel’s killing of Hezbollah head Hassan Nasrallah last week and Hamas political leader Ismail Haniyeh at the end of July. The largely thwarted attack has been seen by many as an attempt to restore the Islamic Republic’s capacity to deter further Israeli attacks on its allies. But with Israel’s armed forces moving into southern Lebanon and the US government unflinching in its support of Netanyahu’s administration, the warning seems to be falling on deaf ears.
