The attack in San Diego this week has been an illustration of the dangers of not paying attention to violent far-right extremism.

If you're trying to wrap your head around NatSEC priorities, under the Trump administration, there are worse places to start than the brand new just unveiled-unveiled document United States counter-terrorism strategy.

I'm Mary Louise Kelly. It's Thursday, which means on this podcast we are diving into the week's biggest national security stories with NPR reporters who are out in the world covering them.

Two of our finest here this week here in the studio with me, NPR National Security correspondent, Greg Myrie. Welcome back.

Hi. Thanks, Mary Louise.

And Odette Yusuf, who reports on extremism for NPR from her home base in Chicago.

Odette, welcome back.

Glad to be here.

Hey, so it is just afternoon here on this somewhat gloomy Thursday in Washington.

Odette, I'm thinking last time you were on the podcast was back in November and now we're practically on summer and Memorial Day is looming time flies.

We have spent, well, we've spent the last few weeks, the last few months talking about international news, whether war in the Middle East or recently this big summit in Beijing,

toward the end of this episode. So please make sure you stick around for that.
