Moshe Ya'alon - Israeli Minister of Defence (2013-2016)

Stephen Sackur speaks to the former Israeli defence minister Moshe Ya'alon, who has become a harsh critic of prime minister Netanyahu.

On the face of it, Israel has achieved a form of stability - led by the same man for eight years, locked in a state of hostile non-communication with the Palestinians, confident of strong support from Washington.

But look a little deeper and cracks appear. Prime minister Netanyahu is under investigation and Israeli society appears ill at ease with itself. How fragile is Israeli unity?
