Iran-Israel war offers Taiwan lessons in deterring China

A war that became a test case

Israel’s surprise strikes on Iran’s nuclear and military infrastructure on June 13, 2025, quickly turned into something larger than a regional clash. Over 12 days, Israel and Iran fought a long-range missile and drone war across about 2,000 kilometers, the first modern conflict of its kind between countries without a shared border. That distance matters for Taiwan because it shows how deterrence now depends not only on firepower, but on whether a society can absorb, adapt, and keep functioning under sustained pressure.

The early lesson from the fighting was blunt. Analysts said Israel’s opening blows severely impaired Iranian air defenses and hit strategic installations, while Iran’s response stayed restrained enough to avoid full-scale escalation. That combination, damage on one side and measured retaliation on the other, is exactly why officials and analysts in Taipei began treating the war as more than a Middle East event. It became a live example of how a democracy can be pressured by a far larger adversary without immediately collapsing.

What Taiwan sees in Iran’s survival

The appeal of the analogy is easy to understand. Iran demonstrated that a state can still complicate an attack after losing key assets, if it has dispersion, resilience, and an ability to respond asymmetrically. In Taiwan’s political debate, that has translated into a simple question: which parts of that behavior can actually be copied, and which are specific to Iran’s geography, command structure, and regional posture?

Taiwan’s representative to Israel, Abby Ya-Ping Lee, said she had been sharing firsthand lessons from the war back to Taiwan. That reflects how quickly the conflict entered Taiwan’s security conversation. The war was not just read as a military exchange, but as a case study in defending a democracy against a larger hegemon, with political endurance seen as part of deterrence itself.

There is another reason Taipei paid attention. Taiwan has relied on the United States as its security guarantor since 1949, and Beijing has long used disinformation to weaken Taiwanese confidence in Washington’s reliability. In that context, any demonstration that a smaller partner can survive an initial shock carries symbolic weight. It does not replace American support, but it can reinforce the argument that Taiwan must be able to endure long enough for outside help to matter.

Where the analogy breaks down

The limits are just as important as the lesson. Iran and Taiwan face different adversaries, different geography, and different alliance structures. Iran can trade strikes across a vast land frontier and through regional proxies. Taiwan is an island, dependent on air and sea routes, and facing a powerful neighbor with much shorter lines of attack and far greater leverage over the surrounding environment.

That difference changes the meaning of dispersion and resilience. For Iran, the war showed that even after strikes on production sites and air defenses, a state can remain dangerous and politically intact. For Taiwan, survival would depend less on sustaining a long regional exchange and more on preventing a rapid coercive campaign from isolating the island. The island’s defense problem is not identical to Iran’s, even if some of the tactical lessons overlap.

Experts have also disagreed on what the war means for deterrence in East Asia. Some argue that a clear U.S. show of force in one theater could help discourage Beijing from moving on Taiwan. Others warn that if Washington’s attention or military resources are pulled away from the Indo-Pacific, China may see an opportunity to test American resolve. The same war can therefore be read either as a warning to Beijing or as a distraction for Washington.

Taipei’s answer: build a layered defense

Taiwan’s defense ministry has already drawn a practical conclusion from the missile-and-drone exchanges: expensive interceptors alone cannot cope with mass attacks. That is pushing Taipei toward a layered air-defense concept often described as Taiwan Shield or T-Dome, which combines indigenous development with foreign procurement of lower-cost interceptors.

The logic is straightforward. If an attacker can force defenders to spend vastly more to stop cheap drones or missiles, the defender loses the economics of the fight even before losing territory. Taiwan’s shift toward cheaper interceptors is meant to reverse that imbalance, while preserving high-end systems for the threats they are actually best suited to defeat. In other words, Taiwan is trying to make endurance affordable.

That is the part of the Iran lesson most relevant to the island. Not the idea of copying Iran’s military model, but the broader recognition that defense has to survive saturation, attrition, and psychological pressure at the same time. A layered system can buy time, and time is the currency of deterrence when the enemy is expected to seek a quick decision.

Israel as a political signal to Taipei

The war also sharpened Taiwan’s diplomatic thinking about Israel itself. Taiwan’s foreign minister, Lin Chia-Lung, said Taiwan wanted to deepen ties with Israel because Israel had shown support for Taiwan unmatched by other Middle Eastern countries. That matters in Taipei because partnerships are measured not only by trade or technology, but by the willingness to stand publicly with Taiwan under pressure.

The conflict has therefore become a lens through which Taiwan weighs its own resilience and its external relationships at the same time. It is not simply asking whether Israel can teach a tactical lesson. It is asking whether democracies under threat can show enough mutual support to make coercion less attractive in the first place.

China’s interest in the broader contest

Iran’s relationship with China adds another layer to the comparison. Reporting indicates that Iran continued cooperating with China to replenish its solid-fuel ballistic missile stockpile after Israeli strikes destroyed Iranian production sites in October 2024. That suggests resilience is not only about surviving damage, but about restoring capacity after it is hit.

For Beijing, the Middle East war is uncomfortable in a different way. Analysts have argued that it exposed China’s lack of leverage there, even as it complicates U.S. Indo-Pacific planning. Beijing can study the conflict, draw lessons from it, and even profit from the distraction, but it cannot easily shape the outcome. That is a reminder that deterrence is not only about weapons; it is also about influence, logistics, and the ability to sustain political will.

For Taiwan, the most useful lesson is not that Iran is a model to copy. It is that a smaller polity can sometimes survive far more than an attacker expects, if it plans for dispersion, layered defense, and political endurance from the start. The harder truth is that Taiwan must do this under far tighter geographic constraints, against a nearer and more capable adversary, and with no room for illusion.
