Chinese President Xi Jinping has made it abundantly clear that “reunifying” Taiwan with mainland China is a legacy issue for him, something he intends to accomplish on his watch through political and economic means or, if necessary, through military force. Right now, he is preoccupied with the COVID-19 crisis, the slowing growth of the Chinese economy, and the upcoming 20th Party Congress, where he hopes to secure a third term as chair of the Chinese Communist Party. But once these immediate concerns are addressed, it is possible that sometime in the next five years Xi will consider taking Taiwan by force, either because nonmilitary efforts at reunification have fallen short or because he believes his chances of success will diminish if he waits and U.S. military capabilities grow.
The long-standing U.S. policy of “strategic ambiguity” deliberately leaves uncertain whether and under what circumstances the United States would defend Taiwan against a Chinese invasion. But it is clearly in the United States’ interest to deter China from attempting such an operation in the first place. As the scholar Hal Brands noted in a July report for the American Enterprise Institute, a Chinese assault on Taiwan that draws a U.S. military response is likely to ignite a long conflict that escalates beyond Taiwan. Like great powers that have gone to war in the past, the United States and China would grow more committed to winning as a conflict progressed, each making the case to its public that it has too much to lose to stop fighting. Given that China and the United States both have substantial nuclear arsenals, preemptively deterring a conflict must be the name of the game. To do so, the United States must help Taiwan modernize and enhance its self-defense capabilities while also strengthening its own ability to deter China from using force against the island.
