In May, the leading British general in the anti-ISIS coalition in Iraq disputed White House claims of an increased Iranian threat. But the foreign secretary, Jeremy Hunt, sided with Washington against his own military officer on the ground. Unlike its European partners, Britain joined the US in swiftly blaming Iran for the subsequent attacks on Gulf shipping. And when Washington urged London to seize an Iranian oil tanker off the coast of Gibraltar this month, the British obliged.
On 9 August, a Saudi Arabian air strike on a school bus in Yemen killed 40 children aged betweeen six and eleven, along with eleven adults, wounding a further 79. The 500-pound bomb had been supplied by the US. It might just as easily have come from the UK. Around half the Saudi air force consists of British-built planes, which have played a significant role in the war.
