The Ministry of National Defense on Tuesday delivered its Quadrennial Defense Review (QDR) to the Legislative Yuan, the first such report since 2021. The QDR serves as a roadmap for military planning over the subsequent four years, and is designed to assess security threats, outline defense strategies and guide military development to safeguard national security.
This year’s QDR reflects continuity and evolution. While deterrence and asymmetric warfare remain at the core, this year’s review places greater emphasis on multilayered deterrence, Taiwan-US military cooperation and countering “gray zone” threats, signaling a more proactive approach to defense. It also emphasizes the need to learn from global conflicts, and adopt an adaptive approach to tactical and technological change, while leveraging Taiwan’s unique territorial advantages.
The emphasis on deepening military exchanges with the US is one of the most significant shifts in this year’s report. While previous reviews acknowledged the importance of US support, this year’s goes further, calling for high-level strategic dialogues and exchanges between the two nations. Key initiatives it lists include expanding intelligence sharing, greater participation in joint tabletop exercises and increased observation of US military drills. This reflects China’s growing military assertiveness and the US’ increasing openness to deeper Taiwan-US defense force collaboration.
Like its 2021 predecessor, the latest edition reaffirms Taiwan’s commitment to asymmetric warfare, with “resolute defense and multi-domain deterrence” remaining a central principle.
It also emphasizes the need to deepen asymmetric capabilities that would make any potential invasion costly for Beijing. It also calls for leveraging Taiwan’s rugged terrain and developing the nation’s indigenous defense industry to enhance “adaptability, agility, lethality, cost-effectiveness and stealth.”
With its focus on innovation and reform, this year’s QDR shows the nation’s military is heeding lessons from recent global conflicts, such as Russia’s war in Ukraine, where decentralized warfighting and drones have played pivotal roles.
A key evolution in this year’s QDR is the heightened focus on countering “gray zone” threats. In the 2021 version, the tactics were discussed in a dedicated section, but this year’s version integrates “gray zone” threats into the broader strategic environment analysis and expands the military’s strategy to address them. This shows that the military is thinking about China’s sub-threshold operations, aware that its psychological operations, disinformation campaigns, and air and sea incursions are part of an integrated strategy.
Another area of continuity is the approach to civil defense and national mobilization. The 2021 QDR underscored the importance of preparing the civilian population for potential conflict. This year’s review expands on that, emphasizing the need for improved training for reservists and whole-of-society defense resilience. The review calls for a more comprehensive approach to national defense, encouraging public preparedness and the need for seamless collaboration between civilian sectors and the military.
This year’s QDR shows that military leadership intends to continue to push through command and control, and training reforms, while prioritizing innovation and asymmetric warfare. However, greater attention is also brought to deepening the nation’s capabilities across various domains, reflecting Beijing’s growing full-spectrum pressure on Taiwan, such as air and sea incursions and psychological warfare.
However, the QDR is a strategic military document and not a policy blueprint. With many Chinese Nationalist Party (KMT) lawmakers and pan-blue media figures hostile to deepening military reform, those interested in ensuring Taiwan’s strength and unity must put the KMT’s feet to the fire so it does not obstruct defense reforms.
President William Lai (賴清德) and wider civil society must ensure the QDR is properly implemented and the trend of reform continues.
In their recent op-ed “Trump Should Rein In Taiwan” in Foreign Policy magazine, Christopher Chivvis and Stephen Wertheim argued that the US should pressure President William Lai (賴清德) to “tone it down” to de-escalate tensions in the Taiwan Strait — as if Taiwan’s words are more of a threat to peace than Beijing’s actions. It is an old argument dressed up in new concern: that Washington must rein in Taipei to avoid war. However, this narrative gets it backward. Taiwan is not the problem; China is. Calls for a so-called “grand bargain” with Beijing — where the US pressures Taiwan into concessions
The term “assassin’s mace” originates from Chinese folklore, describing a concealed weapon used by a weaker hero to defeat a stronger adversary with an unexpected strike. In more general military parlance, the concept refers to an asymmetric capability that targets a critical vulnerability of an adversary. China has found its modern equivalent of the assassin’s mace with its high-altitude electromagnetic pulse (HEMP) weapons, which are nuclear warheads detonated at a high altitude, emitting intense electromagnetic radiation capable of disabling and destroying electronics. An assassin’s mace weapon possesses two essential characteristics: strategic surprise and the ability to neutralize a core dependency.
Chinese President and Chinese Communist Party (CCP) Chairman Xi Jinping (習近平) said in a politburo speech late last month that his party must protect the “bottom line” to prevent systemic threats. The tone of his address was grave, revealing deep anxieties about China’s current state of affairs. Essentially, what he worries most about is systemic threats to China’s normal development as a country. The US-China trade war has turned white hot: China’s export orders have plummeted, Chinese firms and enterprises are shutting up shop, and local debt risks are mounting daily, causing China’s economy to flag externally and hemorrhage internally. China’s
During the “426 rally” organized by the Chinese Nationalist Party (KMT) and the Taiwan People’s Party under the slogan “fight green communism, resist dictatorship,” leaders from the two opposition parties framed it as a battle against an allegedly authoritarian administration led by President William Lai (賴清德). While criticism of the government can be a healthy expression of a vibrant, pluralistic society, and protests are quite common in Taiwan, the discourse of the 426 rally nonetheless betrayed troubling signs of collective amnesia. Specifically, the KMT, which imposed 38 years of martial law in Taiwan from 1949 to 1987, has never fully faced its
