The nations of Western Europe, long divided by feuds far more bitter than any which existed among the 13 colonies, are today joining together, seeking, as our forefathers sought, to find freedom in diversity and in unity, strength.
The United States looks on this vast new enterprise with hope and admiration. We do not regard a strong and united Europe as a rival but as a partner. To aid its progress has been the basic object of our foreign policy for 17 years. We believe that a united Europe will be capable of playing a greater role in the common defense, of responding more generously to the needs of poorer nations, of joining with the United States and others in lowering trade barriers, resolving problems of commerce, commodities, and currency, and developing coordinated policies in all economic, political, and diplomatic areas. We see in such a Europe a partner with whom we can deal on a basis of full equality in all the great and burdensome tasks of building and defending a community of free nations. It would be premature at this time to do more than indicate the high regard with which we view the formation of this partnership. The first order of business is for our European friends to go forward in forming the more perfect union which will someday make this partnership possible.
