But political saber rattling could irreparably damage a fragile geopolitical balance and is sharpening fears of miscalculations in hot spots like Taiwan or the South China Sea. It's also provoked a buzzy debate over a possible US-China cold war that could define the 21st century, just as the US standoff with the Soviet Union colored the post-World War II world.
But that concept of a decades-long frozen standoff between two rival nuclear powers doesn't quite capture the breadth and dynamism of the US-China duel. The coming showdown will be less of an ideological struggle than an active competition in technology, manufacturing, trade, infrastructure and artificial intelligence, for overseas markets, for military superiority and the strategic edge in Asia.
