Don’t Go Backward on China Policy

Foreign Affairs | Ali Wyne, Ryan Hass

U.S. President Donald Trump has undercut American capacity to protect strategic interests regarding China and diminished Washington’s role as an Asian security provider during his second term. By prioritising personal ties with Chinese leader Xi Jinping during high-profile diplomacy, such as their September 2026 Washington summit, the U.S.

administration has discounted long-standing bilateral friction points. Washington lost vital diplomatic leverage. This personalist approach weakens structural bargaining power against Beijing while creating severe uncertainty across the Indo-Pacific region. Simultaneously, persistent presidential criticism of traditional regional allies and partners has forced allied capitals to hedge against American strategic unreliability. Consequently, U.S. security guarantees face gradual erosion across Asia as partner states re-evaluate their collective defense dependencies. Published on 29 October 2026 by policy analysts Ali Wyne and Ryan Hass, the assessment demonstrates how neglecting structural institutional competition in favour of transactional leader-level diplomacy compromises broader deterrence postures, directly destabilising established regional security architecture.

Comment

When American presidential posture relies on personalist leader summits rather than institutionalised coordination, alliance frameworks like the U.S.-Japan Security Treaty face systematic structural devaluation. Bilateral confidence erodes rapidly when key regional capitals observe Washington treating long-standing defense commitments as transactional bargaining chips rather than fixed strategic anchors. This uncertainty forces Indo-Pacific partners to hedge by quietly building autonomous intelligence capabilities and expanding bilateral security ties independent of American facilitation.

A comparable dynamic emerged following the 1969 Guam Doctrine, when President Richard Nixon’s policy shift forced regional partners like Australia and Japan to reassess the operational reliability of the ANZUS Treaty and Asian defense umbrellas. Just as Nixon’s unannounced strategic recalibration compelled regional capitals to diversify their security dependencies half a century ago, presidential detachment from established Indo-Pacific commitments today weakens institutional alliance cohesion across the Western Pacific.

Strategic Question for Discussion

Which factor exerts greater influence on allied defense planning across the Western Pacific: historical precedents of unilateral shift like the 1969 Guam Doctrine, or current operational ambiguities surrounding the U.S.-Japan Security Treaty?

The available evidence points toward immediate operational ambiguities within the U.S.-Japan Security Treaty as the primary driver of current hedging behaviour. While the 1969 Guam Doctrine established a historic baseline for allied skepticism, modern Indo-Pacific capitals react more directly to real-time transactional signals that threaten immediate bilateral deterrence credibility. Consequently, regional states are prioritizing short-term autonomous capabilities while maintaining structural security ties where possible.
