For decades, peace across the Taiwan Strait has rested on a fragile equilibrium maintained through the US policy of strategic ambiguity, whereby Washington deliberately avoids clarifying whether and how it would respond to a conflict between China and Taiwan.
The ambiguity is intended to deter Beijing from launching a military invasion and Taipei from declaring formal independence. But as geopolitical tensions rise and power balances shift, this ambiguity may no longer serve its stabilizing purpose.
A new approach — dual clarity — could provide a better framework for deterring conflict and preserving peace. With this new posture, the US would communicate two key positions: it would oppose any unilateral declaration of independence by Taiwan and respond decisively to any use of force by Beijing.
The current status quo rests on a precarious balance. On one side, Beijing remains adamant that Taiwan must eventually be unified with China, an objective deemed non-negotiable by the Chinese Communist Party. On the other, Taiwan’s population has grown increasingly assertive in its sense of a distinct identity and in its democratic commitment.
A peaceful unification seems increasingly unrealistic. Polling repeatedly shows limited support in Taiwan for any form of unification with China.
Formal separation or de jure independence is equally improbable. Taiwan’s government recognizes that a unilateral declaration would provoke a severe response from Beijing.
Immediate independence
At the same time, only a minority of Taiwanese favor immediate independence, with the majority preferring to maintain the status quo. China’s deterrence posture, military, diplomatic, and economic remains effective in blocking the path toward independence.
However, the status quo is fraying under the weight of incompatible political trajectories. Without profound changes it risks collapsing. The key question, then, is not whether to maintain the status quo, but how to reinforce it.
Strategic ambiguity was a product of its time. It allowed Washington to deter both nations without binding itself to automatic intervention or compromising its “one China” policy.
In doing so, it created space for economic integration and political flexibility. That flexibility is now being strained.
China’s growing military power and assertiveness are narrowing the window for ambiguity to function as a credible deterrent. Meanwhile, the Taiwanese public is increasingly aware of its unique identity and status, and strategic ambiguity does little to clarify the boundaries of US support.
In today’s environment, ambiguity not only creates confusion, but it also increases the risks of miscalculation.
Strategic ambiguity
Strategic ambiguity has also become more difficult to sustain diplomatically. Despite reaffirming its “one China” policy, Washington has deepened its informal ties with Taipei and expanded its military cooperation, notably since President Donald Trump’s first term.
These shifts have already triggered more aggressive posturing from Beijing. Yet, by refusing to articulate clear boundaries, Washington finds itself stuck between provoking China and failing to reassure Taiwan.
In this evolving context, Washington needs to communicate clearly to both Taipei and Beijing where its red lines lie. A policy of dual clarity would do just that: explicitly commit to defending Taiwan against any unprovoked Chinese attack, while reiterating opposition to any unilateral Taiwanese declaration of de jure independence.
Such a policy would provide a credible deterrent to both sides. Taiwan would be assured of US support in the face of aggression, but would also understand that this support depends on restraint. For China, it would raise the costs of aggression by eliminating doubt over whether the US might intervene.
Importantly, recent surveys suggest the Taiwanese would broadly support such a trade-off. Research has shown that many Taiwanese are willing to sacrifice independence if it means receiving firm commitments from the US in the event of an attack.
From Beijing’s perspective, time is not on its side. The longer the current status quo holds, the more entrenched a separate Taiwanese identity becomes, and the more difficult peaceful unification appears. In this light, strategic ambiguity only intensifies the CCP’s fears that inaction will eventually lead to permanent separation.
By contrast, dual clarity can offer a degree of reassurance. If Taiwan knows it cannot declare independence without losing US support, and if Washington communicates this credibly and consistently, Beijing’s most immediate fear may be alleviated. It will not make unification any easier, but it may reduce the urgency that feeds escalation.
Regional and global implications
Of course, adopting dual clarity would not be without risks. It would represent a significant shift in US policy, and Beijing would likely respond with strong rhetoric and possibly military signaling.
However, such a shift would require coordination with key US allies, particularly Japan and South Korea, whose security interests are closely tied to cross-strait stability. In its most recent defense white paper, Japan stated that “stabilizing the situation surrounding Taiwan is important not only for Japan’s security but also for the stability of the international community.”
A unified message from Washington and its partners could reinforce the credibility of the approach and signal that regional security is a shared responsibility.
Moreover, dual clarity should be paired with broader efforts to elevate Taiwan’s global standing. This includes strengthening bilateral economic relations, increasing Taiwan’s participation in international organizations, and continuing support for its military modernization.
Such measures can fortify deterrence while reinforcing Taiwan’s democratic institutions and international visibility. The Taipei Act of 2019 and the current Taiwan Non-Discrimination Act of 2025 represent a move toward such change.
Dual clarity is not a path to resolution, but a strategy to preserve peace in an increasingly precarious environment. It does not abandon the “one China” policy but clarifies how the US interprets and operationalizes its longstanding commitments.
That said, strategic ambiguity may no longer be sufficient to prevent conflict in an increasingly polarized and militarized Taiwan Strait.
By adopting a policy of dual clarity, Washington can send a firm but balanced message that, while it will not support Taiwanese independence, it will not allow Taiwan to be taken by force. If the US aims to preserve the status quo in the Taiwan Strait, it must recognize that the tools of yesterday no longer meet today’s challenges.
Clarity, when paired with restraint, may offer a better way to preserve the peace.
