The bad news first. The People’s Republic of China now believes it can successfully prevent the United States from intervening in the event of a Chinese invasion of Taiwan or some other military assault by Beijing.
Now the good news. China is wrong—and for one major reason. It apparently disregards the decisive power of America’s nuclear-powered submarines.
Moreover, for economic and demographic reasons Beijing has a narrow historical window in which to use its military to alter the world’s power structure. If China doesn’t make a major military move in the next couple decades, it probably never will.
The U.S. Navy’s submarines—the unsung main defenders of the current world order—must hold the line against China for another 20 years. After that, America can declare a sort of quiet victory in the increasingly chilly Cold War with China.
