The desire to stay out of other people’s wars is understandable, and there is no dishonour in John McDonnell, a Labour neutralist, seeking Liberal Democrat and Green support in parliament to try to block the United States using British bases for attacks on Iran.
But it is not possible for Britain to have nothing to do with the conflict in the Middle East. Our citizens’ standard of living is affected by the closure of the Strait of Hormuz. British expatriates are vulnerable to Iranian missiles in several Gulf countries, which are allies. And British bases, including Cyprus and Diego Garcia, are also within range.
