EXPLANATIONS BELOW
Concept note-1: -Mahan argued that the United States needed a strong navy to protect economic interests. The nation needed strategically placed bases where the fleet could refuel. He said the U.S. needed to establish bases in the Caribbean, build a canal across the Isthmus of Panama and acquire islands in the Pacific.
Concept note-2: -Traditionally the navy embraced a defensive strategy with an emphasis on commerce raiding. In contrast, the navy was asked during the Spanish-American War to gain control of the waters around the Philippine Islands and the Caribbean Sea.
Concept note-3: -The main purpose of sea power has always been to protect friendly shipping from enemy attack and to destroy or hinder the enemy’s shipping-both commercial and military.
Concept note-4: -Alfred Thayer Mahan also argued that modern navies needed repair and coaling stations. Those facilities would not be dependable if controlled by other nations. This reasoning inferred a rationale for American acquisition of port facilities throughout the world.
