The outlook for the Ukraine situation is something we want to discuss again with Waikato University's Professor of International Law Dr Al Gillespie, author of the multi-volume The Causes of War. A number of people have had to interview their keyboards recently when guessing at whether Russian President Vladimir Putin can survive disaster in Ukraine. Writing in The Conversation this week, Professor Gillespie says the real trigger in Ukraine may not be Russia winning the war, but beginning to lose it. At that point, he warns, "the theory and paper wall of a UN system designed to prevent wider conflict and superpowers clashing may disappear in a flash". He joins the show to discuss what Russia may do if it loses in Ukraine.
