In the fall of 2022, Danish authorities scrambled fighter jets to investigate a strange disturbance in the Baltic Sea. What they found was extraordinary.

An enormous geyser had opened up on the water’s surface. It was evidence that something deep below had ruptured with enormous force.

Just days earlier, a team of divers had planted explosives along Nord Stream, a multi-billion dollar network of pipelines carrying Russian natural gas into Germany.

In the days and months that followed, all kinds of theories emerged about who might have staged the attack, and why. Now, after years of investigations, intelligence leaks, arrests, and reporting across Europe, a much clearer picture of what happened that night has emerged.

Bojan Pancevski is the Chief European Political Correspondent for The Wall Street Journal, and the author of the new book ‘The Nord Stream Conspiracy: The Inside Story of the Explosions That Shook the World’

He joins us today to discuss one of the most consequential acts of infrastructure sabotage in recent history and the small group of Ukrainian civilian divers who, according to his reporting, pulled it off.
