The US–Israeli war with Iran has shattered Washington’s hope of concentrating its power on containing China. Instead, the United States is entangled in multiple conflicts while Beijing gains strategic time.

The bombs falling on Iran have extinguished any remaining doubt. The  US-Israeli military campaign has ignited a major regional war. This explosion of violence is the ultimate rebuke to a central promise of US President Donald Trump’s second term: that America could disengage from distant quagmires to focus on confronting China.

Over a year into this administration, the strategic picture affirms the conclusion I  reached last summer: America’s hoped-for single-minded containment of China lies in tatters. The president, who once envisioned a grand disengagement to confront Beijing, now finds himself forced to orchestrate a high-stakes  visit. This is not born of strength, but of stark necessity – a tacit admission that the United States is overextended and requires a pause on its most formidable front.

The war with Iran is the fiercest new “tiger” in a menagerie of conflicts that has inverted the administration’s fundamental premise, having restarted a major war that threatens to draw in proxies from Lebanon to Yemen and destabilise the entire region. In Europe, the Ukraine war grinds into its  fifth year. Trump’s boasts of a swift resolution have dissolved into the grim reality of a prolonged, costly commitment he now presides over. The  intervention in Venezuela simmers,  threats against Cuba have resurfaced and the  Gaza conflict persists. Rather than freeing resources, his presidency is ensnared in a web of multi-front crises, each sapping strength.

Even the trade war has backfired; the Supreme Court  ruling that his tariffs overstepped his authority has clipped his wings, exposing the limits of unilateralism.

The goal of rallying traditional allies into a cohesive front against China has been undermined by the “America first” impulse. Now, as Washington needs them most, these nations are engaging in “ calculated hypocrisy”.

Their rush to engage Beijing – the parade of leaders from France’s  Emmanuel Macron and Britain’s  Keir Starmer to Canada’s  Mark Carney and Germany’s  Friedrich Merz – has a clear logic: economic hedging and risk mitigation. Even as they seek this “ third path”, their transactional visits stop well short of challenging the foundational US security alliance – a loyalty reaffirmed by their pro-American statements on the war with Iran.

Nevertheless, the fragility of Trump’s desired coalition has been exposed. America’s diplomatic and military apparatus is catastrophically dispersed globally, leaving the Pacific theatre perennially under-resourced.

This is precisely where China’s ancient strategic wisdom, “sitting on a mountain to watch the tigers fight”, finds potent modern application. Beijing occupies the strategic high ground, observing with calibrated detachment as its principal rival grapples with self-created challenges. The philosophy is not one of passive inertia, but of active, poised restraint.

The Iran war presents a complex but clarifying test of this approach. It disrupts regional stability and threatens Chinese energy interests – a clear short-term setback. Yet, it also perfectly exemplifies the consuming “tiger” Beijing can afford to watch.

China’s response is characteristically pragmatic and long-term. It fights tenaciously for its core interests, yet astutely avoids actions that might relieve American pressure elsewhere. Why would Beijing actively help extinguish the fires in Ukraine or mediate in the Iran war when their very existence consumes and distracts Washington? As noted last year, Beijing does not want to see Russia  lose in Ukraine, fearing a full US pivot to Asia. This enduring patience shapes China’s calculus on Iran.

In the short term, it will call for calm and an end to the conflict. In the long run, its position remains fundamentally unchanged: it will deal with whoever holds power in Tehran. If the conflict leads to regime change, Beijing will swiftly work to restore relations, prioritising stability. However, if – as seems more likely – the war hardens anti-American resistance in Iran, then Washington will have sunk into a deeper, more intractable quagmire, extending and exhausting US resources and giving China even more strategic space.

Thus, Trump’s pursuit of dialogue with Beijing is a symptom of this dynamic, not a strategic reset. It is a tactical manoeuvre born of desperate necessity. The administration, strained by a hot war, the Ukraine stalemate and a hobbled trade toolkit, seeks a temporary de-escalation to buy breathing room. The frontal assaults of the  trade and  tech war have failed to cripple China’s rise, instead  spurring its self-reliance.

Washington now seeks to manage the competition, not end it. From its vantage point, China can afford to receive this overture with composed pragmatism. It negotiates from relative stability, having used the strategic respite to bolster economic resilience and deepen partnerships, including the resilient alignment with Russia that Trump’s policies failed to fracture.

The trajectory remains unchanged from the assessment of eight months ago, only more pronounced. The US is not the focused, relentless pursuer of containment it aspired to be. It is an overstretched power. The war in the Middle East is not a distraction from the China challenge; it is the embodiment of the strategic overextension that makes a coherent China policy impossible.

China, by contrast, exercises strategic patience. It sits on its mountain, watches the tigers below exhaust themselves, and secures for itself the one commodity geopolitics most prizes: time. Trump’s journey to Beijing will be a negotiation, but its very occurrence is a testament to the shift in strategic initiative – forged not in the Pacific, but in the burning sands where America is once again fighting all the tigers at once.
