What did Alfred T. Mahan say that the us needed?

Alfred T. Mahan emphasized the importance of naval power for national strength and global influence in his influential work, "The Influence of Sea Power upon History." He argued that the United States needed a strong navy, overseas bases, and a robust merchant marine to protect its interests and trade routes. Mahan believed that control of the seas was essential for achieving economic prosperity and asserting military dominance in the international arena. His ideas significantly influenced U.S. naval policy and expansionism in the late 19th and early 20th centuries.
