ATLANTIC. President Roosevelt issues proclamation that an unlimited national emergency confronts the United States, requiring that American military, naval, air, and civilian defenses be readied to repel any and all acts or threats of aggression directed toward any part of the Western Hemisphere. In a separate address to the nation to acquaint it with the “cold, hard fact” that the conflict in Europe has developed into a “world war for world-domination,” the President announces that the Atlantic Neutrality Patrol has been extended and that the Atlantic Fleet, greatly increased during the past year, is being constantly built up. He also mentions the dangers posed by “Nazi battleships of great striking-power” that pose “an actual military danger to the Americas,” undoubtedly a reference to the recent operations of German battleship Bismarck. The President states the national policy is two-fold: active resistance “to every attempt by Hitler to extend his Nazi domination to the Western Hemisphere, or to threaten it” and his every attempt to gain control of the seas, and giving “every possible assistance to Britain and to all who, with Britain, are resisting Hitlerism or its equivalent with force of arms.” The delivery of supplies to Britain, Roosevelt tells the nation, “is imperative. This can be done; it must be done; it will be done.”
