The roots of "decisive battle doctrine" are the Russo-Japanese war, in which Japan destroyed the entire Baltic fleet of the Russian Navy at once. The war effectively ended in a day.

Pearl Harbor was supposed to be another one-stroke Samurai thing where the U.S. Navy loses a lot of strength and the rest gives up. This backfired because the U.S. had more industry than Japan and could hold out long enough to make more ships, although it was close and could have gone badly (see: Coral Sea).

Now China has the GDP, population, and industry advantage over the Pacific. The U.S. isn't WWII Japan and (probably, idk, sometimes my country does crazy shit) won't try a Pearl Harbor strike on China, but if they attack Taiwan then the Chinese defeat should be decisive and quick rather than challenging an economically bigger opponent to a long war.
