I have told my sons that they are not under any circumstances to take part in massacres, and that the news of massacres of enemies is not to fill them with satisfaction or glee. I have also told them not to work for companies which make massacre machinery, and to express contempt for people who think we need machinery like that.
American planes full of holes and wounded men and corpses took off backwards from an airfield in England. Over France a few German fighter planes flew at them backwards sucked bullets and shell fragments from some of the planes and crewmen. They did the same for wrecked American bombers on the ground and those planes flew up backwards to join the formation. The formation flew backwards over a German city that was in flames. The bombers opened their bomb bay doors exerted a miraculous magnetism which shrunk the fires gathered them into cylindrical steel containers and lifted the containers into the bellies of the planes. The containers were stored neatly in racks. The Germans below had miraculous devices of their own which were long steel tubes. They used them to suck more fragments from the crewmen and planes. But there were still a few wounded Americans though and some of the bombers were in bad repair. Over France though German fighters came up again made everything and everybody as good as new. When the bombers got back to their base the steel cylinders were taken from the racks and shipped back to the United States of America where factories were operating night and day dismantling the cylinders separating the dangerous contents into minerals. Touchingly it was mainly women who did this work. The minerals were then shipped to specialists in remote areas. It was their business to put them into the ground to hide them cleverly so they would never hurt anybody ever again.
Rosewater was twice as smart as Billy, but he and Billy were dealing with similar crises in similar ways. They had both found life meaningless, partly because of what they had seen in war. Rosewater, for instance, had shot a fourteen-year-old fireman, mistaking for a German soldier. So it goes. And Billy had seen the greatest massacre in European history, which was the fire-bombing of Dresden. So it goes. So they were trying to re-invent themselves and their universe. Science fiction was a big help.
