Over the course of 700 years, the ancient Roman Empire grew from a small republic to one that stretched from London to Baghdad at its peak.
As one of the world's first true superpowers, the Empire's achievements included the world's first standing professional army, economic prowess, intellectual growth and governance principles that are commonly regarded as the basis for modern society.
But it is also remembered for its spectacular collapse in less than a century under the weight of bad debt, an overextension of the Empire, a collapse of morals that led to a deluded and self-absorbed political elite and reckless public spending that far outweighed collections.
Given the parallels to our situation, I can only imagine what Romulus Augustus, widely considered to be the last of the Roman Emperors, would tell President Barack Obama today about how to prevent the wholesale destruction of our own "Empire."
But it would probably go like this…
Cara praeses Obama, (Dear President Obama)
Like mine, your world is changing fast. No doubt it's very different from the one you thought you'd inherited. Your success will depend on new thinking and an eye to the future taken from lessons of the past.
I wouldn't be offended if you have never heard of me.
I oversaw the dying days of what you know as the Classic Western Roman Empire. My fall in September 476 marked the end of centuries of greatness and the fall of ancient Rome.
Some historians consider my departure as the beginning of the Middle Ages. I understand the nature of collapse: how it begins, how it progresses, and where it all ends.
As a historical footnote to a once great empire, here's my advice to you, Mr. President.
