How, then should the United States and its allies approach the question of deterring China? Mastro emphasized three conditions that U.S and Japanese defense policy must meet.
First, whatever the United States and Japan do in the defense realm must have an operational impact. For example, U.S. carriers will do nothing to prevent China from taking Taiwan in a wartime scenario, Mastro argued. “And along those lines, from the Japanese point of view, enhancing defense of the Senkaku Islands does nothing to deter China from taking Taiwan unless Japanese operations are going to be involved directly in stopping a Chinese invasion of Taiwan.”
The second condition is that China has to know about any defense changes the U.S. and its allies are making. For instance, if, in peacetime, there is no indication that the Japanese military is engaging in Taiwan Strait transits with the United States and the Chinese do not know about such activities, then they do not enhance deterrence.
Third, deterrence must happen before a war starts. It may seem an obvious point, but if the prevalent view is that, for example, the Japanese public will support the United States once a conflict over Taiwan erupts, then this approach does not deter China. “We have to let the Chinese know now that there is such support,” Mastro stated.
One issue China is concerned about, Mastro noted, is widening a Taiwan contingency. “China only wins Taiwan if the war is short, geographically limited to Taiwan, and only involves the United States, potentially in Taiwan,” she explained. “So I am convinced that if Japan were to commit to fighting with the United States in this contingency, that would be enough to deter China.”
Ultimately, the question before the United States and its allies is: “Do we want a happy China that is undeterred or an unhappy China that's deterred,” Mastro concluded. “Those are our only two options.” Deterrence is expensive and requires tradeoffs, but one thing that is costlier than deterrence is a major war, she emphasized.
“Let’s start thinking about how to actually change the environment with the sense of urgency that we need, because my biggest fear is that we're going to find ourselves in a major war with massive cost,” she urged the audience. There will be sacrifices to make, but the alternative, in Mastro's view, is worse.
Opportunities and Perils for Democracy
In the second session of the conference, panelists Larry Diamond and Francis Fukuyama examined the war in Ukraine and the tensions over Taiwan from the lens of democratic decline and its implications for the liberal international order.
Democracy has been in a global recession for most of the last two decades, yet the picture is not as bleak for democracies as it was just two or three years ago, said Diamond. In the United States, reforms at the state level have occurred, election deniers took control of Congress seats by a much smaller margin than predicted before the 2022 midterms, and extreme election deniers in crucial swing states were virtually defeated. Meanwhile, on the international stage, 2022 spotlighted autocrats’ inevitable shortcomings. In Russia, Putin has catastrophically miscalculated the war in Ukraine. In China, Xi has massively mismanaged the COVID pandemic, and the country’s economic growth is severely impaired.
