Last week, Iran’s Islamic Revolutionary Guard Corps shot down a US Navy RQ-4A Global Hawk drone over the strategically important Strait of Hormuz. US President Donald Trump initially ordered an attack on Iranian radar sites and missile bases, but called it off at the eleventh hour, substituting the bomb raids with a casualty-free cyberattack.
This conflict is an example of the innovative/asymmetric model of modern warfare, and could serve as an important lesson as Taiwan prepares its defensive deployments and upgrades its military.
Corps Aerospace Commander Ali Hajizadeh has said that Iran could have shot down a crewed P-8A maritime reconnaissance aircraft, but instead targeted the drone as a warning to the US not to invade Iran’s airspace.
That Iran was able to accurately assess multiple targets flying close to its territorial airspace despite not having fighter jets monitoring or tailing the US aircraft suggests that it was relying on electronic intelligence.
Iran’s challenge to the US military’s close-in reconnaissance tactics flies in the face of “freedom of overflight” and “freedom of navigation” operations conducted by many countries in the past few years. These operations have included military planes and warships periodically passing through the crowded and narrow Taiwan Strait.
Taiwan’s military uses radar, early-warning aircraft, maritime patrol vessels, combat air patrols and visual identification by fishing vessels. This should be complemented by including open-source intelligence, such as flight data from the ADS-B Exchange and automatic identification systems, into a joint intelligence detection system to provide the most up-to-date possible picture of maritime and airspace movements.
The Chinese People’s Liberation Army (PLA) is possibly modeling itself on US military tactics and employs electronic-warfare/jammer aircraft with Harbin BZK-005 high-altitude, long-range reconnaissance drones, which conduct encirclement “drills” around Taiwan. Harbin drones are stationed on the Zhoushan archipelago in the East China Sea and Woody Island (Yongxing Island, 永興島) in the South China Sea.
In April last year, one of them was intercepted by Japan’s Self Defense Force in the East China Sea. If a PLA drone enters Taiwanese airspace and uses its optic-electric sensor systems and electronic warfare pod to capture imagery and conduct electromagnetic spectrum analysis, that would enable the PLA to find dead spots within the Taiwanese military’s reconnaissance satellite system and test its electronic attack capability.
The US Cyber Command has been set up to function in coordination with Central Command, but this structure has the potential to cause bureaucratic inertia. The two commands should be separated, along the lines of the Iranian military’s rocket and missile launch system. This presents an information operations challenge where Taiwan’s military urgently needs to make a breakthrough. This technology was frequently mentioned in connection with North Korea’s multiple ballistic missile test launches in 2017, while China Central Television has reported that information operations forms an element of the PLA’s anti-ballistic missile training.
Whether through use of drones or a cyber “first strike” designed to paralyze an enemy nation’s missile systems, such tactics are the only meaningful way to conduct an innovative/asymmetric war. At a time when US-Taiwan military exchanges are at their best, Taipei should waste no time putting together a shopping list of electronic countermeasures and information operations equipment.

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
US President Donald Trump and Chinese President Xi Jinping (習近平) were born under the sign of Gemini. Geminis are known for their intelligence, creativity, adaptability and flexibility. It is unlikely, then, that the trade conflict between the US and China would escalate into a catastrophic collision. It is more probable that both sides would seek a way to de-escalate, paving the way for a Trump-Xi summit that allows the global economy some breathing room. Practically speaking, China and the US have vulnerabilities, and a prolonged trade war would be damaging for both. In the US, the electoral system means that public opinion
