If there is any one continuing theme which will run through my remarks, it is that the basic attitudes which Americans bring to perplexing problems of foreign policy has changed remarkably little since the early days of the Republic. The world, however, and especially the United States itself, has changed a good deal, and it is therefore hardly surprising to find that American foreign policy has changed along with it, for if one applies old ideas to new situations, one is likely to get new policies.
