RIP Taiwan?

In sum, a powerful China isn’t just a problem for Taiwan. It is a nightmare.

How does Taiwan fit into this story? The United States has a rich history of close relations with Taiwan since the early days of the Cold War, when the Nationalist forces under Chiang Kai-shek retreated to the island from the Chinese mainland. However, Washington is not obliged by treaty to come to the defense of Taiwan if it is attacked by China or anyone else.

Regardless, the United States will have powerful incentives to make Taiwan an important player in its anti-China balancing coalition. First, as noted, Taiwan has significant economic and military resources and it is effectively a giant aircraft carrier that can be used to help control the waters close to China’s all-important eastern coast. The United States will surely want Taiwan’s assets on its side of the strategic balance, not on China’s side.

Second, America’s commitment to Taiwan is inextricably bound up with U.S. credibility in the region, which matters greatly to policy makers in Washington. Because the United States is located roughly six thousand miles from East Asia, it has to work hard to convince its Asian allies—especially Japan and South Korea—that it will back them up in the event they are threatened by China or North Korea. Importantly, it has to convince Seoul and Tokyo that they can rely on the American nuclear umbrella to protect them. This is the thorny problem of extended deterrence, which the United States and its allies wrestled with throughout the Cold War.

If the United States were to sever its military ties with Taiwan or fail to defend it in a crisis with China, that would surely send a strong signal to America’s other allies in the region that they cannot rely on the United States for protection. Policy makers in Washington will go to great lengths to avoid that outcome and instead maintain America’s reputation as a reliable partner. This means they will be inclined to back Taiwan no matter what.

While the United States has good reasons to want Taiwan as part of the balancing coalition it will build against China, there are also reasons to think this relationship is not sustainable over the long term. For starters, at some point in the next decade or so it will become impossible for the United States to help Taiwan defend itself against a Chinese attack. Remember that we are talking about a China with much more military capability than it has today.

In addition, geography works in China’s favor in a major way, simply because Taiwan is so close to the Chinese mainland and so far away from the United States. When it comes to a competition between China and the United States over projecting military power into Taiwan, China wins hands down. Furthermore, in a fight over Taiwan, American policy makers would surely be reluctant to launch major attacks against Chinese forces on the mainland, for fear they might precipitate nuclear escalation. This reticence would also work to China’s advantage.

One might argue that there is a simple way to deal with the fact that Taiwan will not have an effective conventional deterrent against China in the not-too-distant future: put America’s nuclear umbrella over Taiwan. This approach will not solve the problem, however, because the United States is not going to escalate to the nuclear level if Taiwan is being overrun by China. The stakes are not high enough to risk a general thermonuclear war. Taiwan is not Japan or even South Korea. Thus, the smart strategy for America is to not even try to extend its nuclear deterrent over Taiwan.

There is a second reason the United States might eventually forsake Taiwan: it is an especially dangerous flashpoint, which could easily precipitate a Sino-American war that is not in America’s interest. U.S. policy makers understand that the fate of Taiwan is a matter of great concern to Chinese of all persuasions and that they will be extremely angry if it looks like the United States is preventing unification. But that is exactly what Washington will be doing if it forms a close military alliance with Taiwan, and that point will not be lost on the Chinese people.

It is important to note in this regard that Chinese nationalism, which is a potent force, emphasizes how great powers like the United States humiliated China in the past when it was weak and appropriated Chinese territory like Hong Kong and Taiwan. Thus, it is not difficult to imagine crises breaking out over Taiwan or scenarios in which a crisis escalates into a shooting war. After all, Chinese nationalism will surely be a force for trouble in those crises, and China will at some point have the military wherewithal to conquer Taiwan, which will make war even more likely.

There was no flashpoint between the superpowers during the Cold War that was as dangerous as Taiwan will be in a Sino-American security competition. Some commentators liken Berlin in the Cold War to Taiwan, but Berlin was not sacred territory for the Soviet Union and it was actually of little strategic importance for either side. Taiwan is different. Given how dangerous it is for precipitating a war and given the fact that the United States will eventually reach the point where it cannot defend Taiwan, there is a reasonable chance that American policy makers will eventually conclude that it makes good strategic sense to abandon Taiwan and allow China to coerce it into accepting unification.

All of this is to say that the United States is likely to be somewhat schizophrenic about Taiwan in the decades ahead. On one hand, it has powerful incentives to make it part of a balancing coalition aimed at containing China. On the other hand, there are good reasons to think that with the passage of time the benefits of maintaining close ties with Taiwan will be outweighed by the potential costs, which are likely to be huge. Of course, in the near term, the United States will protect Taiwan and treat it as a strategic asset. But how long that relationship lasts is an open question.

SO FAR, the discussion about Taiwan’s future has focused almost exclusively on how the United States is likely to act toward Taiwan. However, what happens to Taiwan in the face of China’s rise also depends greatly on what policies Taiwan’s leaders and its people choose to pursue over time. There is little doubt that Taiwan’s overriding goal in the years ahead will be to preserve its independence from China. That aim should not be too difficult to achieve for the next decade, mainly because Taiwan is almost certain to maintain close relations with the United States, which will have powerful incentives as well as the capability to protect Taiwan. But after that point Taiwan’s strategic situation is likely to deteriorate in significant ways, mainly because China will be rapidly approaching the point where it can conquer Taiwan even if the American military helps defend the island. And, as noted, it is not clear that the United States will be there for Taiwan over the long term.

In the face of this grim future, Taiwan has three options. First, it can develop its own nuclear deterrent. Nuclear weapons are the ultimate deterrent, and there is no question that a Taiwanese nuclear arsenal would markedly reduce the likelihood of a Chinese attack against Taiwan.

Taiwan pursued this option in the 1970s, when it feared American abandonment in the wake of the Vietnam War. The United States, however, stopped Taiwan’s nuclear-weapons program in its tracks. And then Taiwan tried to develop a bomb secretly in the 1980s, but again the United States found out and forced Taipei to shut the program down. It is unfortunate for Taiwan that it failed to build a bomb, because its prospects for maintaining its independence would be much improved if it had its own nuclear arsenal.

No doubt Taiwan still has time to acquire a nuclear deterrent before the balance of power in Asia shifts decisively against it. But the problem with this suggestion is that both Beijing and Washington are sure to oppose Taiwan going nuclear. The United States would oppose Taiwanese nuclear weapons, not only because they would encourage Japan and South Korea to follow suit, but also because American policy makers abhor the idea of an ally being in a position to start a nuclear war that might ultimately involve the United States. To put it bluntly, no American wants to be in a situation where Taiwan can precipitate a conflict that might result in a massive nuclear attack on the United States.

China will adamantly oppose Taiwan obtaining a nuclear deterrent, in large part because Beijing surely understands that it would make it difficult—maybe even impossible—to conquer Taiwan. What’s more, China will recognize that Taiwanese nuclear weapons would facilitate nuclear proliferation in East Asia, which would not only limit China’s ability to throw its weight around in that region, but also would increase the likelihood that any conventional war that breaks out would escalate to the nuclear level. For these reasons, China is likely to make it manifestly clear that if Taiwan decides to pursue nuclear weapons, it will strike its nuclear facilities, and maybe even launch a war to conquer the island. In short, it appears that it is too late for Taiwan to pursue the nuclear option.
