Walker,Stephen. Shockwave:Countdown to Hiroshima. Harper Perennial.

 "This is the greatest thing in history"(p.294)

 Harry Truman, then the president of the United States said like above when he was informed of the success of dropping the first atomic bomb to Hiroshima.

 Now many people, especially Japanese people know what had happened in August 6th and 9th,1945. As far as I'm concerned, I thought I know something about the tragedy. But actually I know little about it.

 This book makes me think slight difference in the history might change the result.

 What if so-called Trinity experiment had been failed?

 What if Franklin Roosevelt had lived longer?

 What if Indianapolis had been sunken before arriving at Tinian?

  After she brought the atomic bomb to Tinian Indianapolis had been attacked and sunk.

 What if Enola Gay failed to take off and crushed?

 She is said to be overloaded with Little Boy, which is the first atomic bomb dropped to the real human beings.

 What if people in Hiroshima hadn't been used to siren without any serious air raid?

 What if Enola Gay had been attacked by Japanese aircraft and fallen en route to Hiroshima?

 What if the weather in that day had been different?

 In reading this book I'd always been mutttering to myself ,"What if , What if, What if,・・"

I wanted to prevent the first dropping. But if I want the different path of history I want other people to die. Would I really like to wish their death?

 "But history kept its course."(p.226)

 Nothing changed. Roosevelt died and Truman took over him. Indianapolis succeeded in carrying the bomb. Enola Gay took off and any enemy didn't appear on way. Many people in Hiroshima who were used to siren and all clear didn't expect fierce bomb attack. And the A-bomb was released.

 "Nine days after the sky collapsed over Hiroshima, the war had finally ended. For many of the survivors, however, the struggle was just beginning."(p.308)

 We can't change the past. Can we change the future?


 "How long will the war affect me?"
