Donnacha Ó Beacháin is Professor of Politics at Dublin City University. He will have been seen and heard on the media by many people since the Russian invasion of Ukraine in February, as he is an expert on post–Soviet politics, among many other things.

For a First Thought session at this year's Galway International Arts Festival, he was in conversation with Ruadhán Mac Cormaic, Irish Times Assistant Editor and author of The Irish Supreme Court and was joined remotely from Kyiv by Oleksandr Bohomolov, Director of Ukraine's National Institute for Strategic Studies, which advises the government on all aspects of policy.

They discussed the origins of the conflict, its progress and possibilities for the future, ranging from a troubled peace to an unimaginable World War 3 - watch above.
