In 1958, a movie about a man-eating, bloodcurdling mass from outer space introduced the world to "The Blob." But in recent years, that term has taken on a whole new meaning among foreign policy professionals in Washington. What exactly defines this Blob can be as amorphous as the movie monster, so we reached out to three people to explain who exactly belongs in this group. The term, we learned, describes a perspective that transcends party lines and has remained relatively unchallenged for decades. In this new episode of "Things That Go Boom," The World's partner podcast from PRX, host Laicie Heeley explores the moment all of that changed, and the Blob came face-to-face with ... the anti-Blob.
