According to mahan what world changes have have occured that required the US to re-think its traditional naval strategy?

Alfred Thayer Mahan argued that significant changes in global politics, technology, and maritime commerce necessitated a reevaluation of U.S. naval strategy. The rise of industrialization and the expansion of global trade increased the importance of securing sea lanes and maritime chokepoints. Additionally, new technologies, such as steam power and ironclad ships, transformed naval warfare, requiring a stronger emphasis on battleship fleets and overseas bases to project power. Mahan's perspective urged the U.S. to adopt a more proactive and expansive naval strategy to safeguard its interests and maintain global influence.
