Ada: The whole partnership lasted just twenty-two months. On the twenty-second of June, nineteen forty-one, Hitler launched Operation Barbarossa - the largest invasion in human history - straight across the border he'd agreed to respect.
Theo: So Stalin's champagne partner turned on him after all. Did Stalin see it coming?
Ada: He'd been warned repeatedly and refused to believe it. The oil and grain were still rolling west almost until the tanks crossed.
Theo: And that secret page - the one that officially didn't exist. It just stayed buried?
Ada: For fifty years, Moscow flatly denied it. But the Germans had microfilmed their copies, and those films survived the war in Western hands. The evidence was there the whole time.
Theo: So when did the Soviets finally admit it?
Ada: Not until the twenty-fourth of December, nineteen eighty-nine. A commission under Alexander Yakovlev reported to the Congress of People's Deputies, and the Soviet Union at last confessed the protocol was real.
Theo: Fifty years to admit a single page of paper.
Ada: And the people it had carved up answered first. On the twenty-third of August, nineteen eighty-nine - fifty years to the day - around two million Estonians, Latvians, and Lithuanians joined hands in a human chain stretching across all three countries. They called it the Baltic Way.
Theo: Two million people, holding hands over a border deal they were never told about.
Ada: That's why the twenty-third of August is now a European day of remembrance. So think back on the whole strange arc - the swastikas borrowed from a film studio, the toast to Hitler's health, and a page of paper that two enemies swore never existed.
Theo: And what stays with me is how ordinary people became lines on a map they never saw, and then, half a century later, physically stood on those lines to tear them up.
Ada: That's the lesson, really. Rulers can redraw the world in a single evening - but the people they never consult have a way of outlasting the secret.
Theo: There's a whole darker chapter in what the Soviets did to captured Polish officers in that eastern zone - the Katyn massacre - and it's one tap away if you want it.
Ada: And you can always interrupt us mid-episode and ask whatever you're wondering - we're right here.
Theo: This was Historai - where history answers back.
