Michael Mullen, the former chairman of the Joint Chiefs of Staff, is concerned enough about the risk of war between the United States and China that he is listening to the audiobook version of Barbara Tuchman’s “The Guns of August,” the classic history of how the major powers in 1914 stumbled into World War I.

“I think this is the most dangerous time since I was a kid in 1962,” during the Cuban missile crisis, he told me. “The world war potential is really, really significant.”

I came to Taiwan to gauge that risk and assess how to manage it better. For what it’s worth, I greatly respect Admiral Mullen — few people know as much about global hot spots and how wars happen — but my best guess is that Americans may be overestimating the risk of conflict, particularly of an all-out invasion of Taiwan by China.

Moreover, I worry that American anxiety about the risk of war with China may inadvertently exacerbate it. “The Guns of August” is, as Mullen noted, a useful prism for reminding us how miscalculation, misunderstanding and escalation created a world war that no one wanted. So we should be alert not only to the risk that China poses to peace in the region but also to the risk we Americans unintentionally pose, and to the possibility that our legitimate efforts to confront China can lead to accidents at sea or air that lead to war.

There is a fine line between deterring China and provoking it. My take is that while we should do significantly more to help Taiwan boost defenses and deter aggression, we should do so quietly, without needlessly humiliating China. Sometimes Americans loudly embrace Taiwan in ways that inflame tensions at times when we should be hoping to lower them.

Let me also make the case that we think too much in terms of an invasion — when the greater risk may be China’s taking lesser nibbles to pressure Taiwan, leading to the possibility of accidents and escalation that could drag us into an unintended world war, as happened in 1914.
