With the worsening situation of North Korea’s nuclear capabilities, South Korean media are reporting that US President Donald Trump’s administration has made it known to China that, should it fail to exert pressure on Pyongyang, it will consider allowing Seoul and Tokyo to develop nuclear weapons.
The domino effect of this decision could even see Taiwan following suit, something China absolutely would not accept.
When Chang Hsien-yi (張憲義), former deputy director of the First Institute of the Chungshan Institute of Science and Technology (CSIST), defected to the US in 1988, Taiwan was secretly developing nuclear weapons.
Had that incident happened in a Northeast Asia with possible nuclear proliferation, would the US still have stopped the program? Or would the US have tacitly allowed it, as it did with Israel, enabling Taiwan to boost its deterrence capability while lowering the US’ costs in preventing it from being taken by China?
North Korea’s nuclear weapons development program appears to have progressed rapidly in a short time and there is a real possibility that it will soon be able to strike the US.
Several opinion polls of South Koreans show that more than 60 percent place little faith in the US’ nuclear umbrella, and actually support their country developing nuclear weapons.
The US is also concerned that a larger nuclear threat comes from China.
According to an official US report, within the next 15 years China could have more than 100 nuclear bombs capable of reaching the US. During the 1995-1996 Taiwan Strait missile crisis, China let slip that it did not believe the US cared more about Taipei than about Los Angeles.
The Chang Hsien-yi incident occurred during the Cold War, when two considerations colored the US’ position.
First, the US did not believe China was capable of or willing to attack Taiwan. The People’s Liberation Army (PLA) was weak, neither fully capable of troubling Taiwan nor dealing with the Soviet threat. It needed the US’ protection, albeit indirectly, and attacking Taiwan would have been against its own interests, as Beijing would not have wanted to risk offending the US.
Things are different now. Beijing is both capable and willing.
Second was concern over initiating a domino effect on nuclear proliferation in Northeast Asia.
Even though the area was nuclear-free, each player — not just South and North Korea, Taiwan and Japan — could conceivably develop nuclear weapons within a short period.
Now, the first domino has already been tipped by North Korea and it is not only South Korea that is concerned.
Japanese Prime Minister Shinzo Abe has said that Japan’s development of a small-scale defensive nuclear weapon would not contravene the nation’s pacifist constitution.
If all nations in Northeast Asia gained nuclear weapons, could the US oppose Taiwan joining in?
For Taiwan to rely solely on conventional weapons in the face of the PLA’s rapid development makes it increasingly difficult for us to protect ourselves from China. Many national defense ministers have said that Taiwan could only repel a PLA invasion attempt for between two and four weeks. What happens after that? Can it really rely on the US’ security assurances?
Opinion polls in the US show that fewer than 20 percent of Americans support going to war with China over Taiwan. On the other hand, the US is unlikely to be prepared to see China take Taiwan as its own.
For these reasons, the emerging situation might convince the US to tacitly agree to Taiwan boosting its own, independent deterrent.

In the US’ National Security Strategy (NSS) report released last month, US President Donald Trump offered his interpretation of the Monroe Doctrine. The “Trump Corollary,” presented on page 15, is a distinctly aggressive rebranding of the more than 200-year-old foreign policy position. Beyond reasserting the sovereignty of the western hemisphere against foreign intervention, the document centers on energy and strategic assets, and attempts to redraw the map of the geopolitical landscape more broadly. It is clear that Trump no longer sees the western hemisphere as a peaceful backyard, but rather as the frontier of a new Cold War. In particular,
When it became clear that the world was entering a new era with a radical change in the US’ global stance in US President Donald Trump’s second term, many in Taiwan were concerned about what this meant for the nation’s defense against China. Instability and disruption are dangerous. Chaos introduces unknowns. There was a sense that the Chinese Nationalist Party (KMT) might have a point with its tendency not to trust the US. The world order is certainly changing, but concerns about the implications for Taiwan of this disruption left many blind to how the same forces might also weaken
As the new year dawns, Taiwan faces a range of external uncertainties that could impact the safety and prosperity of its people and reverberate in its politics. Here are a few key questions that could spill over into Taiwan in the year ahead. WILL THE AI BUBBLE POP? The global AI boom supported Taiwan’s significant economic expansion in 2025. Taiwan’s economy grew over 7 percent and set records for exports, imports, and trade surplus. There is a brewing debate among investors about whether the AI boom will carry forward into 2026. Skeptics warn that AI-led global equity markets are overvalued and overleveraged
As the Chinese People’s Liberation Army (PLA) races toward its 2027 modernization goals, most analysts fixate on ship counts, missile ranges and artificial intelligence. Those metrics matter — but they obscure a deeper vulnerability. The true future of the PLA, and by extension Taiwan’s security, might hinge less on hardware than on whether the Chinese Communist Party (CCP) can preserve ideological loyalty inside its own armed forces. Iran’s 1979 revolution demonstrated how even a technologically advanced military can collapse when the social environment surrounding it shifts. That lesson has renewed relevance as fresh unrest shakes Iran today — and it should
