Tom Wiegele had a very special influence on my life, as he did on the lives of many. He was first my teacher, then my mentor, my colleague, and, most importantly, my friend. It was easy to be infected by Tom's enthusiasm for his work. Although trained in traditional international relations theory, Tom was convinced that all politics, including international relations, is fundamentally the behavior of human beings. The more one understands about humans as humans, the better one's explanations of political behavior will be.
