In The Shadows Of The American Century

As the dust settled after World War II, America controlled half the world's manufacturing capacity. By the end of the Cold War it controlled nearly half the planet 's military forces, spread across eight hundred bases, and much of its wealth. Beyond what was on display, the United States had also built a formidable diplomatic and clandestine apparatus. Indeed, more than anything else, it is this fourth tier of global surveillance and covert operations that distinguishes the US from the great empires of the past.
But even as it has used satellites, drones and cyberwarfare capabilities to secure an unrivalled global power network, its share of the global economy has diminished, its diplomatic alliances have begun to weaken and it has abandoned its claim to moral leadership. Meanwhile, China is emerging as the world's largest economy, poised to integrate the world island, stretching from Shanghai to Madrid and lay claim to the South China Sea.
