Should the United Kingdom use nuclear weapons against Iran?

Tensions escalate as the UK permits US strikes on Iranian sites from British bases like Diego Garcia and RAF Fairford, prompting Iran to fire ballistic missiles at Diego Garcia, demonstrating a 4,000 km range reaching European capitals. Iran advances uranium enrichment to 60% purity, nearing weapons-grade levels, while arming proxies like Hezbollah and Houthis against regional targets including British interests. The UK maintains its Trident nuclear deterrent and deploys a nuclear submarine to the Arabian Sea amid fears of Iranian missile threats to sovereign territory like Cyprus.
