European nations have demanded that Donald Trump justify the growing human cost of the conflict at the Strait of Hormuz, declining to send warships and calling for urgent diplomatic efforts to stop the escalating casualties. Trump’s warnings about NATO’s future were seen in European capitals as an attempt to sidestep accountability for a conflict that had already caused thousands of deaths and had the potential to generate thousands more. European leaders argued that any military strategy that could not justify its human cost against realistic prospects of success was not one they could support.
Germany’s leaders were the most direct in raising the human cost dimension. Chancellor Friedrich Merz noted that the scale of civilian casualties in Iran and the mounting toll among American troops made the case for urgent diplomatic engagement overwhelming. Defense Minister Boris Pistorius combined the humanitarian argument with a strategic critique, arguing that adding European ships to the conflict would add military resources without adding strategic clarity. Together, they made Germany’s refusal both principled and morally grounded.
Keir Starmer of the United Kingdom acknowledged the growing humanitarian consequences of the conflict while maintaining his policy of constructive but non-committal engagement. He promised a plan developed through broad multilateral consultation and confirmed the UK would not be drawn into the wider conflict without proper backing. Trump remained critical of London but continued to believe Britain would eventually contribute.
Italy, Greece, France, Japan, and Australia all declined to participate. The EU confirmed that Operation Aspides would not be expanded following Monday’s ministerial meeting. Kaja Kallas noted the absence of member state appetite for changing the mission’s mandate. Estonia continued to call for strategic clarity and accountability from Washington and Tel Aviv.
Human rights organizations reported that more than 1,800 people had been killed in Iran, with over 1,200 being civilians, while US forces confirmed 13 dead and more than 200 wounded. Fresh Israeli strikes on Iranian cities, retaliatory missile fire, and drone attacks on UAE energy and air operations continued to add to the toll. Iran rejected ceasefire proposals and warned against US ground deployment.
