The precision of British intelligence assessments has been underscored by Iran’s missile attack on two Iraqi bases housing American troops. The assault, launched in the early hours of Wednesday, involved more than a dozen ballistic missiles fired from Iranian territory. It marked a significant escalation in the standoff between Washington and Tehran following the killing of General Qassem Soleimani.
Whitehall sources have confirmed that UK intelligence agencies had warned their American counterparts of a potential Iranian retaliation within 48 hours of the Soleimani strike. The assessment, compiled by MI6 and GCHQ, drew on intercepted communications and satellite imagery indicating that Iran’s Islamic Revolutionary Guard Corps had placed its short-range missile systems on high alert. The British warning was dismissed by some US officials as overly cautious.
The attack, while causing no casualties, damaged aircraft, runways and structures at the Ain al-Asad airbase in Anbar province and another facility in Erbil. The Pentagon acknowledged that its own intelligence had underestimated both the speed and scale of the response.
The episode reinforces the reputation of British intelligence as a sober voice within the Five Eyes alliance, often tempering more aggressive assessments from Washington. Yet it also raises questions about the coordination between allies. The US decision to withdraw Patriot missile batteries from the region in the months before the attack has been criticised by defence analysts in London.
Downing Street has expressed support for the US response, calling the attack a “clear violation of international law”. The prime minister is expected to brief parliament on the intelligence-sharing failures later this week. The Foreign Office has advised British nationals to leave Iraq and Iran immediately.
