Take the following as truth: The slang of one military generation passes on to the next, so the Marines who called the Koreans gooks in the '50s and the Vietnamese gooks in the '60s and '70s were the linguistic heirs of the Marines who called the Nicaraguans gooks in 1912.
Then the following statement: "New military slang terms were created in the 1980s." is true, false, or inconclusive?
Answer: Inconclusive
