In a historic rebuke to the White House, the US Congress has voted to limit President Donald Trump’s authority to launch military action against Iran, a move that comes as Britain’s quiet diplomacy in the Gulf helps keep the vital Strait of Hormuz open for global trade. For working families across the Midlands and the North, this is not a distant geopolitical game: it is about the price of petrol, the cost of heating a home, and the security of jobs in ports and factories that rely on stable supply chains.
The vote in the House of Representatives, which saw cross-party support, reflects deep unease about a potential war many MPs here have long warned would be a catastrophe for ordinary people. The Resolution on Iran War Powers, passed with a comfortable majority, insists that any prolonged engagement must be authorised by Congress. It is a direct challenge to a president who has veered between fiery threats and bewildering overtures to Tehran. For British workers remembering the 2003 Iraq invasion and the decade of military spending that sucked resources from schools and hospitals, this feels like a vindication of the anti-war movement’s long slog.
Meanwhile, the diplomatic route Britain has quietly championed is showing results. The Strait of Hormuz, a narrow waterway through which a fifth of the world’s oil passes, had been a flashpoint since attacks on tankers last year. But a deal brokered by British officials, involving a maritime security framework called Operation Sentinel, has reduced tensions. The Royal Navy’s HMS Montrose and HMS Duncan have been escorting UK-flagged vessels, but more importantly, London has been working behind the scenes with Oman and Iraq to keep dialogue alive. Last week, a joint statement from the UK, France, and Germany – the E3 – reaffirmed commitment to the JCPOA nuclear deal, despite Trump’s withdrawal.
For the average family in Sunderland or Stoke, the immediate benefit is stability at the pumps. Oil prices, which spiked after the US drone strike that killed General Qasem Soleimani in January, have eased. Petrol now averages 123p a litre, down from 130p in early January. But the relief is fragile. “If the Strait closes, we are looking at £1.50 a litre within weeks,” says Janet Brown, a mother of two from Doncaster who runs a small cleaning business. “That means cutting back on food or not turning the heating on.”
The economic stakes are high. The UK exports £6bn worth of goods to the Gulf annually, and imports 10% of its oil from the region. Ports like Felixstowe and Southampton handle containers that feed into the warehouses of Amazon and Tesco. A war would disrupt these flows, pushing up inflation and squeezing already tight household budgets. The Trades Union Congress has echoed these concerns, urging the government to resist any US pressure to join military action. “Our members do not want another Middle Eastern war paid for by cuts to public services,” says TUC General Secretary Frances O’Grady.
Critics on the left argue that Britain must go further. While the government has supported the congressional measure in spirit, it has not formally endorsed it. Labour MPs, including shadow foreign secretary Emily Thornberry, have demanded a Commons vote on any future military involvement. The SNP has called for a full parliamentary debate. But with Boris Johnson’s government focused on Brexit trade talks, the issue has slipped down the agenda.
For now, the Strait of Hormuz remains open, and the oil keeps flowing. But the lesson from Congress is clear: the power to wage war cannot be left to a single, unpredictable leader. Britain, with its history of industrial muscle and working-class scepticism of overseas adventures, must keep pushing for peace – not just for moral reasons, but for the bread on every kitchen table.
