I want to know the answer to the following question:
In what year did the study in Cryptologic Spectrum come out?
All the background I'm provided with is that "In 2013 a lot of media coverage was given to unclassified NSA's study in Cryptologic Spectrum that concluded that Tito did not speak the language as a native, and had features of other Slavic languages (Russian and Polish).". Is that enough to answer the question?
Answer: yes
