Iran’s missile attack sends a message – but can it deter the Israeli offensive in Lebanon?

Iran launched a retaliatory missile barrage on Israeli military infrastructure Tuesday in response to Israel’s killing of Hezbollah chief Hassan Nasrallah last week and Hamas political leader Ismail Haniyeh in July. The largely thwarted attack was 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 Binyamin Netanyahu’s administration, the warning seems to be falling on deaf ears.
