Sarah Montague speaks to former Catholic priest Oliver McTernan who has spent more than two decades working in conflict resolution in the Middle East. He is the director of the organisation Forward Thinking and was involved in negotiations that led to the release of the Israeli soldier Gilad Shalit in 2011. While he has no formal role in the current talks over the war in Gaza, he regularly speaks to senior figures in both Hamas and the Israeli government. Given the history of this protracted conflict, does he hold any hope that it will ever be resolved?
