ROME, MAY 27, 2004 (Zenit.org).- George Weigel is one of the foremost American Catholic thinkers involved in the current debate on the Catholic just war tradition and modern warfare. Weigel was one of the featured speakers and organizers of a conference last month on "Catholic Thought and World Politics in the 21st Century," at the Gregorian University. I asked Weigel to expound on some of the arguments he raised at the conference, particularly concerning the Church's position on just war, the role of the United Nations and the Holy See's current position on armed intervention.
