The Prime Minister has ordered an emergency review of Britain’s nuclear posture following the collapse of the Iranian deal. This is not a routine audit. It is a strategic pivot born from intelligence failures that have left a hostile state on the brink of weaponisation.
The threat vector is clear: Tehran now has a clear path to a warhead, and our deterrent posture is dangerously exposed. The review must focus on three core vulnerabilities: cyber resilience of Trident command systems, logistics for second-strike capability under degraded communications, and the readiness of the Royal Navy’s continuous-at-sea deterrent. The intelligence community’s failure to foresee the deal’s implosion is a systematic breakdown.
We must assume hostile actors are already mapping our response timelines. The review must be completed in weeks, not months. The next move from Tehran will not wait for Whitehall bureaucracy.
