The excerpt below is from Alfred Thayer Mahan's Influence of Sea Power upon History, published in 1890.
"England's naval bases have been in all parts of the world and her fleets have at once protected them, kept open the communications between them, and relied upon them for shelter... Colonies attached to the mother-country afford, therefore, the surest means of supporting abroad the sea power of a country... Britain's power was everywhere that her ships could reach."
In this book, Mahan urged Americans to build a large navy and acquire colonies as Britain had. What other strategy did Mahan advocate for the United States to succeed as a naval power?
