After two and a half decades, is the United States’ run as the world’s sole superpower coming to an end? Many say yes, seeing a rising China ready to catch up to or even surpass the United States in the near future. By many measures, after all, China’s economy is on track to become the world’s biggest, and even if its growth slows, it will still outpace that of the United States for many years.

And it will give Washington options for dealing with nonstate threats such as terrorism and transnational challenges such as climate change. But it will also impose burdens of leadership and force choices among competing priorities, particularly
