In 2017, the US and a coalition of more than 80 countries ran ISIS out of its strongholds, killed the group's top leaders, and declared victory.

But that wasn't the end.

Instead, ISIS reinvented itself as an even greater threat to the United States homeland—and did so more successfully than any other foreign terror group. National security experts now say a 9/11-style attack is no longer the main worry. It's "domestic terrorism" by "lone-wolf" attackers radicalized online to murder their fellow Americans.

On this episode, we consider how ISIS has revised the radicalization playbook to become "the easiest club in the world to join," as one expert describes. We'll hear how groups embracing other extremist ideologies – including white supremacy, male supremacy and anti-government sentiment - are using that same playbook. And we'll get concrete advice on how to prevent radicalization in young people.
