Messersmith, G.S., Havana. To Sumner Welles, Washington., 1940 May 22

Enclosure: See No. 1361. Transmitting memorandum on alien controls; controls will be called totalitarian measures and violation of civil rights by some, but majority, when they know what is at stake, will realize necessity for controls; suggests Breckinridge Long as best man to head program; envisages results if Germany wins war and dictates peace; she would have at her disposal combined fleets of all Europe and unlimited sources of raw materials and production; doubts U.S., with all her resources, could meet such strength even if given time; Germany would insist on taking over British, French, and Dutch posessions in Western Hemisphere, which U.S. could not permit.
