- Communists of the entire Western Hemisphere are living in Havana […] attacking and discrediting the United States of North America.

- The name United States of America first appears in the Declaration of Independence. The Franco-American treaties of 1778 use the phrase United States of North America, occasionally employed thereafter in official pronouncements; but Congress resolved July 11, 1778, in favor of the name United States of America, to be used on its bills of exchange, and it has been used since as the official name.
Though the phrase was more commonly used by writers of the British Empire, it continued in use in the United States until the 20th century, especially in the context of diplomatic missions to Latin America.
