Lyndon Johnson rarely referred to Hiroshima. On one dramatic occasion he consciously tried to avoid it, but Hiroshima came to the White House, anyway.
The year was 1965. Johnson invited a wide range of painters, sculptors, and writers to the White House for a one-day festival of the arts. Five authors and poets were asked to read from their works. The poet Robert Lowell, protesting the Vietnam War, declined the invitation, explaining that the U.S. "may even be drifting on our way to the last nuclear ruin." But a decision by one of the other writers, who opposed the war but elected to attend the festival, caused just as much anguish at the White House. John Hersey, invited as a novelist, announced that he would read instead from Hiroshima, and he planned to update his account with statistics on the destructive power of existing nuclear weapons.
After discussing the matter with her husband, an enraged Lady Bird Johnson summoned the festival organizer, historian Eric Goldman (then a consultant to LBJ), to the White House. She recited one of the passages Hersey intended to read, which described Truman's announcement of the Hiroshima bombing. "The president is very close to President Truman," she explained icily. "He can't have people coming to the White House and talking about President Truman's brandishing atomic bombs." Then, coming to the point, she complained that her husband was being criticized "as a bloody warmonger. He can't have writers coming here and denouncing him, in his own house, as a man who wants to use nuclear bombs." Goldman explained that Hersey did not believe that Johnson wanted to use nuclear weapons, only that in the nuclear era any war was extremely dangerous. She replied: "The President and I do not want this man to come here and read this." Twice more he objected and twice more she responded with the same words.
Goldman refused to tell Hersey what to do, and the invitation stood. President Johnson, meanwhile, ordered a media blackout of the festival. He also requested FBI background checks on some of the guests.
When Hersey appeared behind the podium at the White House, Lady Bird Johnson was right there in the third row. Hersey prefaced his reading from Hiroshima with the following statement: "We cannot for a moment forget the truly terminal dangers, in these times, of miscalculations, of arrogance, of accident, of reliance not on moral strength but on mere military power. Wars have a way of getting out of hand." Occasionally he lifted his eyes from his text and looked at Lady Bird for emphasis. When Hersey finished, he was greeted by vigorous applause. "The First Lady, who clapped for all other readings, sat motionless," Goldman later reported. And when the president heard about Hersey's reading (and some other activities he viewed as hostile) he cut short his appearance at his own festival.
