The United States was a great power less because of its ideas than because, with direct access to the Atlantic and Pacific oceans, it was the most favored state in the world from the point of view of location.
According to Robert D. Kaplan in "The Revenge of Geography," the strength of the United States as a global power is largely attributed to its advantageous geographical position rather than its ideological principles. The U.S. has direct access to both the Atlantic and Pacific Oceans, which has historically facilitated trade, defense, and connectivity with other nations.
Kaplan emphasizes that this unique location has played a critical role in establishing the United States as a dominant force on the world stage. While ideas and governance certainly contribute to power, he argues that geographical factors are foundational in determining a nation's capabilities and influence in global affairs.
