I recently interviewed Lawrence J. Haas via email about his new book, subtitled “How Jack, Bobby, and Ted Remade America’s Empire” (Potomac Books). The exchanges have been edited for length. Larry, hundreds of books have already been written on Kennedys, so what inspired you to write this one? I knew a bit about Jack and Bobby from my readings over the years, and I watched Ted up close while I worked as a journalist in Washington. I became intrigued when I noticed how involved Ted was with America’s global role because, after all, he’s known overwhelmingly for his domestic achievements (civil rights, labor, health, and so on). I became further intrigued when I took a closer look at what Ted was doing on foreign affairs, which was sometimes consistent with what Jack and Bobby did and sometimes quite different. So, I began to do some research, and I discovered a new, rich, fascinating story about all three brothers.
