When does escalation morph into overreach? On October 8, the one-year anniversary of the first Hezbollah rockets fired on Israel, the IDF is announcing the killing of another top-ranking Hezbollah commander – the heir apparent to Hassan Nasrallah – and the deployment of a fourth division to southern Lebanon.

Militarily, the Israelis have so far been wildly successful, neutralising much of the enemy's leadership and thereby cashing in on years of painstaking intelligence work. But what is the precise objective of it all?

After flattening Gaza for a year, Israel has already forced an estimated 1.2 million Lebanese to flee their homes. To what end? Israelis employ the adage that to make peace, you first need war. We ask our panel if that makes sense, as the world waits for Israel's response to direct rocket attacks by Hezbollah's patron Iran.

And does this escalation serve the interests of Israel's allies? In the United States, talk of brokering a truce alongside France has gone quiet. Is Joe Biden or Binyamin Netanyahu driving policy in Washington?
