Prelude to Leadership: The Postwar Diary of John F. Kennedy

"Kennedy kept wonderful diaries, which are quite useful from a biographer’s perspective, at various points in his life, particularly while travelling. This book, edited by Deirdre Henderson, is composed of what he wrote while he toured Europe in 1945, right after the Germans surrendered and immediately before the Japanese sued for peace. There is a foreword by Hugh Sidney, the journalist, who knew Kennedy quite well. The book is fascinating because it is a window into what a young Kennedy, just decommissioned from the Navy, was thinking as he’s seeing up-close the destruction wrought by World War II in Europe and interacting with a lot of high-powered people. He’s clearly fascinated by politics and by international relations. When he wrote these diaries, it was only about a year and a half since he’d returned from his own service in the Pacific theatre. He’s clearly skeptical about the wisdom of using military power to solve political problems. That’s one thing that comes through in the diaries. At the same time, he makes clear his conviction that the United States must play a leadership role in the new international system that is emerging from the rubble of war. Kennedy is convinced, as he travels in these middle months of 1945, that the United States has newfound responsibilities in the global arena, but that it cannot go it alone; it must work in concert with other nations. He endorses the concept of collective security. There’s no question that Joe Kennedy helped pave the way for JFK, his second son. Through his wealth and through his connections, he made it possible for Jack to undertake these travels both before and after World War II, which proved really important to JFK’s maturation as a thinker and his emergence as a political leader. As you say, I open my book with his travels in Europe in 1939. And though now, in 1945, he is emerging from his father’s shadow, it would have been very hard undertaking these travels, maybe impossible, without the older man’s help. It’s true that Trump and JFK were second sons who lost their older brothers. They were both born to privilege and to wealth. And you can say that there’s one more thing that they had in common, they were both sons of very domineering fathers.

Kennedy was intensely interested in history, interested in international affairs and interested in other countries. He had an openness about other cultures, he understood competing visions of national interest and he was comfortable with complexity. As I say in the book, Kennedy, even as a young man, treated serious things seriously, and thought long and hard about the problems of world affairs, and about the challenges of democratic leadership. He always put a premium on reasoning from evidence. The same could hardly be said of Trump."
