The Likelihood of Invasion

In stark terms, Oriana Skylar Mastro, a center fellow at the Freeman Spogli Institute for International Studies, believes there’s a 100% chance China will use some sort of force against Taiwan in the next five years. For the last twenty years, China has been making concerted efforts to modernize its military and increase its capabilities not only to assert force against Taiwan, but to deter intervention from the United States.

In the majority of scenarios, the United States wins in a conflict with China over Taiwan. But the United States also carries a distinct geographic disadvantage. The distance across the Taiwan Strait between the island and mainland China is approximately 100 miles, which is roughly the distance between Richmond, Virginia and Washington D.C. If China moves quickly, PRC forces could take Taiwan before U.S. forces have time to move into position.

When considering possible outcomes in Taiwan, it is equally important to consider the motivations driving Beijing’s ambitions. The leadership on the mainland has been planning and thinking about how to retake Taiwan since 1949. With the modernized capabilities coming online, the balance of power has shifted in China’s military favor, and the cost-benefit calculus favors Beijing’s ambitions. The long-term planning stage is now reaching its end, and the prospects of direct action are increasing.

The View from Taipei

Political leaders in Taiwan recognize the growing danger they face across the Strait. In Larry Diamond’s assessment, the end of Hong Kong's autonomy and the suppression of the “one country, two systems” model, the rising military incursions into Taiwan's air defense identification zone and coastal waters, and the whole rising pace of Chinese military intimidation has sobered Taiwan and visibly impacted Taiwanese public opinion.

Concerningly though, while the political elite recognize the real and present danger of the situation, polling of the general Taiwan public suggests that the vast majority of citizens still feel like an attack or an invasion by China is unlikely. Similar majorities suggest that they would be willing to fight in Taiwan’s defense, but volunteering for military service remains at a minimum.

To maximize safety, Taiwan needs to find ways to strengthen itself in its ability to defend, resist, and deter China, while still avoiding any appearance of moving toward permanent independence or any other action that could be deemed by Beijing as a provocation, says Diamond.

What the United States Can Do

When it comes to the defense of Taiwan, the strategic crutch hobbling the United States is geography. Most of the U.S. Pacific forces are not in Asia. The majority are in Hawaii and California, as well as a few bases and airfields in Japan. To be able to effectively deter China, the U.S. needs far greater forward deployed military capability in order to be able to either stop or stall the movement of Chinese troops into Taiwan, says Mastro.

Taiwan needs greater onshore military deterrence capabilities as well. One such strategy is the “porcupine approach,” which increases the number of smaller mobile lethal weapons. By Larry Diamond’s assessment, increased citizen participation in military training is also crucial, with an emphasis on weapons training and urban defense tactics. The U.S. could support these aims by overhauling the current system for weapons procurement to speed up the production and delivery of weapons systems not just for Taiwan, but to the benefit of U.S. defense and other contingencies as well. Working with leadership to create strategic stockpiles of food, and energy should also be a priority, says Diamond.

The U.S. also needs to put much more effort into its diplomatic efforts on behalf of Taiwan. Many U.S. allies and partners are reluctant to ostracize China because of economic ties and concerns over sparking their own conflict with China in the future. A key ally in all of this is Japan. If Japan fights with the United States on behalf of Taiwan, it is a guaranteed win and enough to effectively deter China. But much more needs to be done much more quickly in order to secure those guarantees and present them in a convincing way to Beijing.

“The clock is ticking,” Larry Diamond says. “And the problem is we don’t know how fast it’s ticking. “Taiwan is moving in the right direction. But we need to move faster than we're moving.”

Taiwan is currently the single biggest point of contention in U.S.-China relations, and U.S. allies have a crucial role to play in efforts to prevent a great-power war over the island. South Korea, however, has remained relatively ambiguous about its willingness to support U.S. efforts to push back against China’s growing influence in the region, including in the Taiwan Strait. As the Yoon administration is now creating an opening for a more proactive approach, what can South Korea do in a Taiwan contingency?

A new article in The Washington Quarterly provides a framework for analyzing South Korea’s potential role in this era of strategic competition through the lens of war over Taiwan. The authors — Oriana Skylar Mastro, a Center Fellow at APARC, and Sungmin Cho, a professor at the Daniel K. Inouye Asia-Pacific Center for Security Studies — build upon traditional concepts of balancing to create a nuanced, operationally relevant strategy for South Korea to contribute to the defense of Taiwan.

They explain South Korea’s approach to the Taiwan issue to date; evaluate South Korea’s strategic importance and what it can do to support U.S.-led efforts to compete with China; explore how China and North Korea may respond to increased South Korean cooperation with the United States, along with the potential obstacles this cooperation could create; and recommend ways to leverage the US-ROK alliance to enhance deterrence against China with respect to Taiwan.

Mastro and Cho recognize that it is operationally and politically infeasible for South Korea to fight side-by-side with U.S. forces against China in a Taiwan scenario or to build its military sufficiently to deter Chinese aggression against Taipei. South Korean strategists must also consider the costs of China’s and North Korea’s potential responses to greater South Korean involvement in defending Taiwan. Still, Seoul can play a significant role in deterring Chinese aggression.

According to Mastro and Cho, South Korea’s optimal strategy to navigate the U.S.-China rivalry should meet two conditions. First, it should contribute to the vision of a free and open Indo-Pacific, including deterring Chinese aggression against Taiwan. Second, it should be able to make China hesitate to take punitive actions against South Korea. Thus, South Korea can provide rear-area support to the United States, such as intelligence gathering, ammunition supplies, or noncombatant evacuation. It can also support the strategic flexibility of US Forces Korea (USFK) and be more proactive in deterring North Korean aggression and provocation to free up U.S. resources to focus on China in a contingency scenario.

Moreover, South Korea could contribute toward forms of “collective resilience” against China’s economic statecraft, such as collective economic sanctions, and leverage its position as one of the world’s leading producers of advanced semiconductors to complicate China’s calculus. Finally, Seoul’s diplomatic support of U.S.-led efforts to defend Taiwan can influence Beijing to take seriously the international community’s potential united response against any attempt to invade Taiwan.

“Given the heightened urgency over tensions in the Taiwan Strait, Washington and Seoul should pursue these options immediately to maintain peace and stability in the region before it is too late,” the authors conclude.
