Cynical
Considering how likely we all are to be blown to pieces by it within the next five years, the atomic bomb has not roused so much discussion as might have been expected. The newspapers have published numerous diagrams, not very helpful to the average man, of protons and neutrons doing their stuff, and there has been much reiteration of the useless statement that the bomb "ought to be put under international control." But curiously little has been said, at any rate in print, about the question that is of most urgent interest to all of us, namely: "How difficult are these things to manufacture?"
  Such information as we--that is, the big public--possess on this subject has come to us in a rather indirect way, apropos of President Truman's decision not to hand over certain secrets to the USSR. Some months ago, when the bomb was still only a rumour, there was a widespread belief that splitting the atom was merely a problem for the physicists, and that when they had solved it a new and devastating weapon would be within reach of almost everybody. (At any moment, so the rumour went, some lonely lunatic in a laboratory might blow civilisation to smithereens, as easily as touching off a firework.)
     In his piece “You and the Atomic Bomb”, Orwell conveys a cynical tone through carefully selected diction and figurative language.  Written immediately following World War II, Orwell’s essay states his insightful viewpoints toward the Atomic Bomb and the cold war that it will inevitably cause.  Orwell immediately establishes his cynical tone, stating, “considering how likely we are to be blown to pieces by [the atomic bomb]”, a clearly cynical viewpoint toward the power of the atomic bomb to disrupt and devastate humanity.  To Orwell, the atomic bomb is a “devastating weapon” that could be used by some “lonely lunatic in a laboratory” to “blow civilization to smithereens”.  In addition to his cynical viewpoints towards the upheavals that the bomb threatens to inflict upon society, Orwell also conveys cynicism regarding the government’s attempt to hide the project from the public--all information the public possesses on the bomb has come in an “indirect way” and the bomb seems little more than a “rumor”.
