The US Is Sitting There Fat and Happy

Zion makes a powerful case for the US having uniquely amazing geography. He doesn't place a huge emphasis on it, but I really do think that his example nations are Egypt and Mesopotamia. Constantinople lasted a thousand years after the fall of the Western Roman Empire because of its geography. But at some point the technology was developed to destroy those walls,. That was the end of Constantinople. Zion seems curiously uninterested in exploring the possible use of nuclear weapons.
