As Russia invades Ukraine and the country’s government and citizens weigh up the value of continuing resistance, we’ll ask whether Just War theory can offer them any guidance.

We speak to church leaders including the Archbishop of York, Stephen Cottrell, who joins us to discuss the unfolding crisis as well as Bishop Kenneth Nowakowski, who is the head of the Ukrainian Catholic Church in this country.

Ukraine also has a significant Jewish minority and a deep history in Ukraine and Europe. We speak to Volodymyr Vysotsky, from the Jewish Ukrainian Social Initiative who is in Kyiv and providing humanitarian aid to the Jewish community. We also speak to Paul Anticoni, the Chief Executive of World Jewish Relief about the the humanitarian aid that he and other faith organisations are delivering to those in need.
