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.

Concerns that the US might abandon Taiwan are often overstated. While US President Donald Trump’s handling of Ukraine raised unease in Taiwan, it is crucial to recognize that Taiwan is not Ukraine. Under Trump, the US views Ukraine largely as a European problem, whereas the Indo-Pacific region remains its primary geopolitical focus. Taipei holds immense strategic value for Washington and is unlikely to be treated as a bargaining chip in US-China relations. Trump’s vision of “making America great again” would be directly undermined by any move to abandon Taiwan. Despite the rhetoric of “America First,” the Trump administration understands the necessity of
US President Donald Trump’s challenge to domestic American economic-political priorities, and abroad to the global balance of power, are not a threat to the security of Taiwan. Trump’s success can go far to contain the real threat — the Chinese Communist Party’s (CCP) surge to hegemony — while offering expanded defensive opportunities for Taiwan. In a stunning affirmation of the CCP policy of “forceful reunification,” an obscene euphemism for the invasion of Taiwan and the destruction of its democracy, on March 13, 2024, the People’s Liberation Army’s (PLA) used Chinese social media platforms to show the first-time linkage of three new
If you had a vision of the future where China did not dominate the global car industry, you can kiss those dreams goodbye. That is because US President Donald Trump’s promised 25 percent tariff on auto imports takes an ax to the only bits of the emerging electric vehicle (EV) supply chain that are not already dominated by Beijing. The biggest losers when the levies take effect this week would be Japan and South Korea. They account for one-third of the cars imported into the US, and as much as two-thirds of those imported from outside North America. (Mexico and Canada, while
The military is conducting its annual Han Kuang exercises in phases. The minister of national defense recently said that this year’s scenarios would simulate defending the nation against possible actions the Chinese People’s Liberation Army (PLA) might take in an invasion of Taiwan, making the threat of a speculated Chinese invasion in 2027 a heated agenda item again. That year, also referred to as the “Davidson window,” is named after then-US Indo-Pacific Command Admiral Philip Davidson, who in 2021 warned that Chinese President Xi Jinping (習近平) had instructed the PLA to be ready to invade Taiwan by 2027. Xi in 2017
