Johnston's own sixth grade historian Bethany Vaughan's research titled "To Drop the Bomb or Not to Drop the Bomb: That is the Question" was published in the latest issue of The Texas Historian. Bethany's work surrounding the controversy of the justifications for dropping the atomic bomb on Hiroshima and Nagasaki was compiled from her research at the Harry Truman library in Missouri, medical libraries, interviews with people who lived during the time of the bombings, and countless primary sources, books and articles.
