In what ways does the Manhattan Project show a connection to Lord of the Flies?

Lord of the Flies was written in 1954, after the close of WWII and after the Soviet Union had officially become a nuclear state and the Cold War had begun in 1949.
Although the boys are isolated on the island, the background of the novel is that the rest of the world is at war (Ralph's father is a commander in the Navy, the boys are stranded because their own plane was shot down somewhere over the Pacific, and later a soldier's body parachutes down to the island after also being shot down).
Lord of the Flies is related to the Manhattan Project because the Manhattan Project developed the atomic bombs that were used to end WWII in Japan. At the beginning of Lord of the Flies, Piggy announces that no one from the airport is coming to save them because "Didn't you hear what the pilot said? About the atom bomb? They're all dead" (Golding, 7). Lord of the Flies is written after the devastation in Japan that was caused by the atomic bomb and during the Cold War, when several countries were worried about the ongoing threat of nuclear weapons.
