Britain’s wake-up call to the Iranian threat

 Who can credibly say the struggle against the Iranian regime is nothing to do with Britain now? At the height of the US bombing campaign against the ayatollahs, the British government sought to distance itself from the US-Israeli operation, aligning itself with much of Europe in the pretence that the country did not need to directly take sides. Even the attack on RAF Akrotiri on Cyprus by a suspected Iranian drone was not enough to rouse ministers from their complacency. 

Iran has shown no such equivocation towards a country its propagandists still like to refer to as the “Little Satan”. In 2025, the director-general of MI5, Ken McCallum, reported that the agency had tracked more than 20 “potentially lethal Iran-backed plots” in just one year. 

Evidence has grown of the regime’s willingness to use alleged front groups in Britain to further its malign aims. Now the Telegraph reports details of a cyber attack by hackers affiliated with Iran. They are thought to have succeeded in disabling a small British power plant for several days. It may be the most successful cyber attack of its kind to date.

It is understood the outage had no impact on the UK’s power supply or energy generation. Nevertheless, it inevitably raises questions about how prepared the UK is to defend itself against cyber offensives by hostile states or other malicious actors. For years, experts have warned about the vulnerability of the UK’s energy system, especially given the proliferation of internet-connected devices within the network. This attack may have only affected a relatively small site, but it underlines the need for vigilance.

It also emphasises the need for a change of attitude among British policymakers towards the Iran threat. They had to be dragged kicking and screaming towards banning Iran’s Islamic Revolutionary Guard Corps (IRGC), the group integral to exporting Tehran’s noxious ideology beyond its borders. Otherwise, the assumptions that drove the Iran nuclear deal in the 2010s – a belief that the regime can be moderated or constrained, if only we are conciliatory or talk to the right people – still appear to guide policy today. 

That was already naive in 2015. It looks even worse now, given that the Iranian regime appears unwilling to offer Britain any thanks for refusing to take a direct role in Donald Trump’s campaign. If anything, the regime seems determined to double-down on international provocations, despite the destruction wrought by the US military.  

A successful cyber attack against a British power station ought to be a wake up call. Britain needs to take far more seriously the warnings that its essential utilities are vulnerable to hostile penetration. It needs to be far more vigilant against Tehran’s attempt to spread misinformation in British society. But above all, it needs to be able to recognise that Iran is a hostile state, dedicated to undermining the West and our way of life. 

The ayatollahs are not going to wake up one morning and suddenly discover a commitment to liberal democracy and peaceful coexistence. Opinions will differ about how Tehran should be confronted. But complacency about the threat posed by the Iranian regime must end.
