Most analysis written over the past decade assumes that by the middle of the twenty-first century China will overtake the USA and become the leading superpower. For reasons partially discussed in Chapter Two, I am not convinced. It may take a century. Economically the Chinese are on their way to matching the Americans and that buys them a lot of influence and a place at the top table, but militarily and strategically they are decades behind. The USA will spend those decades attempting to ensure it stays that way, but it feels inevitable that the gap will close.
