The greatest present challenge facing America and its allies is arguably a small democratic island off the coast of the biggest rising naval hegemon. Detached historians might see an amusing parallel from ancient Greek history, but history has rarely been kind to small islands caught in the middle of a great-power rivalry. The same argument has now reached Washington D.C., as China embarks on one of the fastest and largest naval build-ups in human history.
Charles Glaser writes for Foreign Affairs that China is geographically poised to take Taiwan if it so desires, yet defending Taiwan militarily is a fool’s errand — impossible to do without an uncomfortable, civilization-destroying cost. According to Glaser, the defense of Taiwan isn’t imperative to the balance of power in Asia, and unlike other allies — such as Japan and Australia — Taiwan is uncomfortably placed in a region where geography gives China an advantage.
That said, in a war the United States might be able to prevail, but the cost of that would be unbearable to generations who have no idea what a genuine great power war might look like. Therefore, Glaser argues that America shouldn’t tie its fate to Taiwan or promise to do something it cannot. Countering Glaser’s assessment in Foreign Policy, Blake Herzinger accuses Glaser of Chamberlain-esque appeasement, arguing that if the United States abandons Taiwan, all hope is lost.
Their debate frames the situation in simplistic Manichean terms, providing only two options: complete abandonment of Taiwan, or catastrophic war mounted in Taiwan’s defense. Yet such bifurcation is flawed, not least of which because it fails to mention a whole host of additional options, from deterrence by a vigorous arming of Taiwan, or by “bleeding” China by way of asymmetric escalation.
Yet the balance of power in place for the last three decades is, unfortunately, unlikely to hold. As scholarly literature suggests, the relative power difference between China and the United States has changed since the early 1990s. As such, any debate about Taiwan should start with these three questions.
