In 1939, the young Irish state stood at a crossroads in its history. Europe was descending into war, and the deeply impoverished and weakly defended nation feared its strategic location on Britain's flank could mean invasion - by either side. In this episode, Naomi and Tim describe a moment when two towering figures of 20th century history came head-to-head and shaped the fates of Ireland, Britain, and Europe. The Irish revolutionary leader Éamon de Valera and Britain's wartime prime minister Winston Churchill had profoundly different starts in life and world views - and they hated each other. Their bitter personal relations led to a Second World War standoff, and a mysterious late-night telegram from Downing Street that constitutes one of the great 'what if' questions of Irish history.

This is part one of a double episode on Irish military neutrality, explaining how the flagship Irish policy came to be. In part two, we'll dig into what Irish military neutrality means in practice today, and the opportunities and challenges ahead as Europe revisits its strategic security in an era in which the United States is in retreat.
