The U.S. faces a major superpower conundrum.
The rise and fall of great powers and their imperial domains has been a central fact of history for centuries. It’s been a sensible, repeatedly validated framework for thinking about the fate of the planet. So it’s hardly surprising, when faced with a country once regularly labeled the “sole superpower,” “the last superpower,” or even the global “hyperpower” and now, curiously, called nothing whatsoever, that the “decline” question should come up. Is the U.S. or isn’t it? Might it or might it not now be on the downhill side of imperial greatness?
Take a slow train — that is, any train — anywhere in America, as I did recently in the northeast, and then take a high-speed train anywhere else on Earth, as I also did recently, and it’s not hard to imagine the U.S. in decline. The greatest power in history, the “unipolar power,” can’t build a single mile of high-speed rail? Really? And its Congress is now mired in an argument about whether funds can even be raised to keep America’s highways more or less pothole-free.
