President Donald Trump has demanded a multibillion-dollar appropriation for military action against Iran, following a rebellion within his own party that threatens to derail his administration’s foreign policy agenda. The request, submitted to Congress late on Wednesday, seeks $15bn to fund a sustained campaign of airstrikes and naval deployment in the Persian Gulf, aimed at crippling Iran’s nuclear programme and its regional proxies. The move comes after a group of Republican senators, led by Rand Paul and Mike Lee, blocked a previous resolution authorising the use of military force, citing constitutional concerns and the risk of a protracted war.
British officials have reacted with alarm, warning that any escalation in the Gulf could trigger a severe oil price shock, destabilising global markets and undermining the fragile economic recovery. The Foreign Office issued a statement emphasising the need for de-escalation and urging the Trump administration to pursue diplomatic channels. “A military confrontation with Iran would have catastrophic consequences for regional stability and the global economy,” said a senior Foreign Office source. “We are actively engaging with our allies to prevent further deterioration.”
The Pentagon has already ordered an additional 5,000 troops to the Middle East, joining the 14,000 deployed since May. The USS Abraham Lincoln carrier strike group remains on station in the Arabian Sea, while B-52 bombers have been stationed at Al Udeid Air Base in Qatar. Defence officials confirm that contingency plans for strikes against Iranian nuclear facilities, missile sites, and naval assets have been refined and presented to the White House.
Iran has responded with characteristic defiance. General Hossein Salami, commander of the Islamic Revolutionary Guard Corps, warned that any attack would be met with “overwhelming force,” including missile strikes on US bases and allies in the region. “If war breaks out, it will be the end of America’s presence in the Middle East,” he said in a televised address. The Iranian foreign ministry has called for an emergency session of the UN Security Council.
The domestic political calculus is fraught. Trump’s demand for funds faces an uphill battle in a deeply divided Congress. House Speaker Nancy Pelosi has described the request as “reckless and illegal,” while Senate Majority Leader Mitch McConnell has expressed reluctance to fast-track the legislation without a clear strategy. The Republican revolt, which saw 15 senators vote against the earlier authorisation, underscores the party’s wariness of another costly conflict in the Middle East. “We cannot afford another endless war,” Senator Paul said. “The president must present a clear plan and a clear exit strategy.”
Analysts suggest that Trump’s brinkmanship may be aimed at forcing Iran to negotiate on his terms, but the risk of miscalculation is high. The International Energy Agency has warned that a disruption to Gulf oil supplies could push prices above $100 a barrel, exacerbating inflationary pressures worldwide. Britain, which imports 8% of its crude from the region, has begun contingency planning for a release of strategic petroleum reserves.
As the crisis deepens, the UK government faces a delicate balancing act: maintaining its alliance with Washington while protecting its economic interests and avoiding entanglement in a conflict with unpredictable consequences. The prime minister is expected to hold emergency talks with European leaders in the coming days. For now, the world watches as the prospects for war grow more tangible by the hour.
