A similar term, "useful innocents", appears in Austrian-American economist Ludwig von Mises' 1947 book, Planned Chaos. Von Mises wrote that the term was used by Communists for liberals, whom von Mises describes as "confused and misguided sympathizers".[15] The term useful innocents also appears in a 1946 Reader's Digest article titled "Yugoslavia's Tragic Lesson to the World", written by Bogdan Raditsa, who had served the Yugoslav government-in-exile during World War II, supported Josip Broz Tito's partisans (though not a Communist himself) and briefly served in Tito's new Yugoslav government before leaving for New York.[16] "In the Serbo-Croat language", says Raditsa, "the communists have a phrase for true democrats who consent to collaborate with them for [the sake of] 'democracy'. It is Korisne Budale, or Useful Innocents".[17]
