If there is any benefit to be realized from the collision between China and the U.S. over Speaker Nancy Pelosi's proposed trip to Taiwan, it is this: America needs to reflect long and hard upon what it is we will fight China to defend in the Taiwan Strait and South China Sea.

China, after all, is a nuclear-weapons nation with a manufacturing base larger than our own, an economy equal to our own, a population four times ours and fleets of warships larger in number than the U.S. Navy.

An air-naval-and-missile war in the Western Pacific and East Asia would be no cakewalk.

A massive barrage of anti-ship and hypersonic missiles launched by China could cripple and conceivably sink the U.S. carrier Ronald Reagan now in the South China Sea. The Reagan carries a crew of thousands of sailors almost as numerous as the U.S. casualty lists from both Pearl Harbor and 9/11, the worst attacks in and on the U.S. outside of such Civil War battles as Gettysburg and Antietam.

What in East Asia or the Western Pacific would justify such losses?

What would justify such risks?
