IISS Assessment Warns of Nuclear Escalation in Taiwan Scenario
The International Institute for Strategic Studies released a 156-page assessment warning that a war over Taiwan could trigger operations against command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) hubs, raising the prospect of nuclear escalation. The report was timed for the Shangri-La Dialogue, the conference in Singapore.
Key Actors and Strategic Context
The assessment focuses on United States, China and Taiwan. Beijing has not ruled out force and prefers peaceful reunification; Taipei rejects Beijing’s sovereignty claim. It follows a summit between President Xi Jinping and President Donald Trump, after which US Defence Secretary Pete Hegseth will speak at Singapore; China’s Defence Minister Dong Jun has not confirmed attendance.
Nuclear Capabilities and the Emerging Arms Race
The report notes Asia-Pacific sits at the centre of a nuclear arms race, with states expanding arsenals and developing conventional strike systems. A December Pentagon analysis projects China to field 1,000 warheads by 2030. The Federation of American Scientists estimates active warheads at 4,400 for Russia, 3,700 for the United States and 620 for China.
Risk of Escalation Without Guard Rails
IISS analysts warn militaries could target each other’s C4ISR nodes without guard rails or agreed rules of engagement. The assessment says there is little public evidence both sides understand the necessary safeguards, and that nuclear escalation will continue to loom large in a major U.S.–China clash.
Official Statements and Responses
Beijing states it prefers peaceful reunification but has not ruled out the use of force; Taipei rejects any claim to sovereignty. U.S. officials have voiced uncertainty about the durability of security guarantees following the Xi-Trump summit.
Criticism & Opposition
IISS notes a lack of mutually understood guard rails and rules of engagement for C4ISR targeting, describing the shortfall as a critical gap in crisis management.
Conflicting Reports & Gaps
Information does not confirm whether Defence Minister Dong Jun will attend the Shangri-La Dialogue, and no bilateral agreements on nuclear escalation control have been disclosed, leaving analysts without safeguards on either side.

- “Regional states and those with strategic interests are expanding their nuclear arsenals, while non-nuclear weapons states pursue long-range conventional-strike capabilities: both challenging strategic stability,” — IISS
- “Conflict with China would risk escalation, potentially to a nuclear level, given the strategic importance of Taiwan to Beijing,” — IISS
- “There is currently little public evidence to suggest that both militaries understand the necessary guard rails to prevent, or rules of engagement that would restrict, both sides potentially targeting each other's key command, control, communications, computers, intelligence, surveillance and reconnaissance nodes,” — IISS
- “A Pentagon report released in December said China was on track to field 1,000 warheads by 2030.” — Pentagon report
What’s Next: Shangri-La Dialogue
The Shangri-La Dialogue runs May 29-31 in Singapore, gathering ministers, generals and intelligence chiefs. Participants are expected to debate the IISS findings, discuss nuclear risk mitigation and explore confidence-building measures while United States and China manage an increasingly contested Indo-Pacific environment.
