Of all the joint ventures in which we might engage, the most productive, in my view, is educational exchange. I have always had great difficulty-since the initiation of the Fulbright scholarships in 1946-in trying to find the words that would persuasively explain that educational exchange is not merely one of those nice but marginal activities in which we engage in international affairs, but rather, from the standpoint of future world peace and order, probably the most important and potentially rewarding of our foreign-policy activities.
