By John Q. Hosedrinker Growing doubts about the United States’ commitment to its allies, particularly under the Trump administration, are causing Japan and South Korea to reconsider their long-held stances on nuclear weapons. High-ranking Japanese officials, including former deputy defense ministers, are openly discussing the possibility of Japan developing its own nuclear arsenal or exploring nuclear sharing with the U.S. This shift is driven by concerns over America’s reliability and the increasing nuclear threat from China and North Korea. Though public opinion in both countries is changing, significant challenges and potential repercussions, including sanctions and international condemnation, remain a major obstacle to any change in existing non-nuclear weapon policies.

Trump shock spurs Japan to think about the unthinkable: nuclear arms. The events unfolding in Ukraine have understandably sparked a global re-evaluation of security. If a nation wants the ultimate deterrent, the conversation now centers on nuclear weapons.
The traditional security blanket for many countries has been their alliance with the United States. However, with a perceived decline in American leadership and a growing unease about its reliability, this assumption is being seriously questioned. A world marked by instability and uncertainty is, unfortunately, a legacy that many associate with Trump’s actions. The focus on “peace” seems to come at the expense of long-term stability. Some believe that his actions inadvertently embolden adversaries, potentially setting the stage for wider conflicts.
For Japan, the realization that the US may not always be a dependable ally is a pivotal moment. The unpredictability of American foreign policy, often swayed by financial interests, casts a shadow over the security guarantees offered. The question then becomes: can Japan truly rely on the US to uphold its commitments, especially when faced with potential short-term gains or internal political pressures? In this environment, the allure of independent nuclear deterrence grows stronger.
The choice before Japan is stark: maintain a reliance on others for security, or take the path of sovereignty and armed self-reliance. This option allows Japan to have the final say in their own security. Given the rising influence of China, the perceived unreliability of the US, and the precedent set by Ukraine, it’s not hard to imagine other nations, like Canada, Poland, and others, considering the nuclear option as well.
The concern isn’t about an imminent US takeover, but rather about a shift in the global power dynamics. In a world where the US might not always be a reliable security partner, nuclear weapons are seen by many as a necessary safeguard. The global community should not be surprised if the proliferation of nuclear weapons becomes a means of self-defense, especially given an unstable, perhaps even fascist, America.
Given its mature nuclear power industry and rocketry program, Japan is also in a strong position to develop nuclear arms. Japan’s position as a country that recycles its used fuel to further its independence, also allows it to produce weapons-grade material, if needed. Many believe that Japan is very close to being able to construct a bomb very quickly. The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.
In this evolving landscape, the strategic advantages offered by nuclear weapons are increasingly recognized. The question of whether to go nuclear is being weighed differently. China’s assertiveness, combined with the perceived unreliability of the US, is compelling many countries to reconsider their reliance on others for protection.
It is understood that this may increase the risk of a nuclear war, but that increase is going to be inevitable regardless, and the proliferation of nukes might be the only viable deterrent nowadays. While the US focus remains on Ukraine, a lot of people believe the US’s sincerity in honoring its commitments to its allies is faltering. The fear of unchecked nuclear threats, combined with the example set by North Korea, is driving Japan to re-evaluate its security strategies.
The discussion around nuclear weapons is shifting from one of taboo to one of necessity. Western allies only? The question has shifted, if other nations get nuclear weapons as well, like Iran, Brazil, or South Africa, then it will be okay too? Or will they get bombed like Iran under the justification of “security concerns”? The idea of an expanding, unchecked nuclear threat does not have a single solution.
Japan is at a critical juncture, forced to confront the question of self-reliance in the face of a changing world. In an era of shifting alliances and unpredictable leadership, the notion of an independent nuclear deterrent is no longer unthinkable. The debate has shifted from whether to consider it, to when. The response is natural. Japan’s pursuit of nuclear capability is driven by geopolitical reality.
