In a span of a single century from the early 20th century, USA has grown from an overseas colony of Britain into a superpower that dominated the world politically, economically and militarily as a seemingly unassailable global hegemon.

How and why this happened, and how this has changed the world beyond recognition are important questions. This is a great story and an enigma that has occupied the minds of historians and laypersons alike to this very day.

How did America evolved from a strapping British overseas colony to become the most powerful nation in the world? How did it prevailed over the powerful British empire and Spanish empire? How did it outperform its European cousins both economically and militarily within a century? And how did it build up its incomparable military might?

How is all this to be sustained in a rapidly changing world? Can America continue its pipe dream of being the eternal empire and of maintaining eternal hegemony?

These are the very important questions for the world that are addressed in this book.
