Any discussion of postwar problems in our relations with Latin America must begin with a consideration of the great changes which have taken place in hemisphere relations during the war period. Since 1939, the American Republics have achieved a degree of coöperation in international matters which would hardly have seemed possible a few years earlier, and today all but one of the nations of the Continent are helping the United States either as belligerents or as non-belligerents in the prosecution of the war.

On the military side, our neighbors have given us bases for our Naval and Air Forces and have strengthened their own armed forces, in most cases with the aid of missions from our Army and Navy. Some of them have taken an active part in anti-submarine operations, and Brazil is preparing to send forces abroad. On the political side, they have set up machinery for coöperation in dealing with fifth column and other hostile activities. The importance of their coöperation in these matters is inestimable. Of still more significance, perhaps, has been their economic aid.
