NPR broadcast a show recently on which the topic of "decoder rings" came up. Somebody objected and the term decoder ring was dropped from the competition.
It was technicality. They were not actual "rings," but structurally they were a ring. Ranger got his in 1955 from an Ovaltine box. The Captain Midnight Show broadcasted the "secret message" weekly, and only those with the decoder were in the know. Ranger faithfully decoded the message weekly, which was usually a preview to the next episode.
If our leaders were good Boy Scouts, and used their decoder rings faithfully and correctly, they would know what is coming up. The decoded message would be:
End the wars.
