Hey, everyone. Welcome to Your Undivided Attention. I am Tristan Harris.

And I'm Azorescan.

So in the fall of 1983, ABC aired this film called The Day After. It was a television event. It was a historic moment.

And it showed in this film the devastating aftermath of what would happen in a possible nuclear war.

It was seen by more than 100 million people on one night, making it the most watched television event in human history.

And it aired during one of the most dangerous moments of the Cold War.

on nuclear war. He no longer saw it as something that the U.S. could win, but rather something

that everyone would lose. And so over the next few years after the movie, Reagan and its Soviet

counterparts began to discuss nuclear disarmament. In 1987, they signed the first ever agreement

to begin cutting down their

nuclear arsenals. So yeah, I mean, it took some time, but over the next few years, Reagan and

some of his Soviet counterparts began discussing what it would take to have nuclear disarmament.

And in 1987, they signed the first ever agreement to actually begin cutting down their nuclear

arsenals.

So the day after wasn't, you know, the magic bullet that solved everything,

but it's an example of the power that a film can have to nudge the world in a different direction.

And it crystallized, you know, a mass movement against nuclear weapons by helping President Reagan fully understand some of the human stakes of his decisions.
