US President Donald Trump has informed top lawmakers that hostilities with Iran "have terminated," a move that sidesteps a legal deadline requiring congressional approval for the military campaign he launched with Israel on 28 February. In letters sent Friday to House Speaker Mike Johnson and Senate president pro tempore Chuck Grassley, Trump stated that "there has been no exchange of fire between United States Forces and Iran since 7 April, 2026" and that the conflict "began on 28 February, 2026, have terminated."
The declaration comes as the Trump administration faces mounting pressure from Congress over the legality of what it calls a "military operation" — a war initiated without prior legislative authorization. The 1 May deadline, set under the War Powers Resolution, would have required Trump to obtain congressional approval or face legal challenges. Republican lawmakers, however, have largely deferred to the president, allowing the deadline to pass without action.
Legal and Strategic Implications
The letter underscores the administration's broad assertion of executive power, a theme that has defined Trump's approach to foreign policy. Despite the claim of terminated hostilities, the US maintains a significant military footprint in the region, including multiple aircraft carriers and naval strike groups, as well as an ongoing blockade of Iranian ports. This continued presence suggests the conflict may be far from resolved, a point Trump himself acknowledged in the letter: "Despite the success of United States operations against the Iranian regime and continued efforts to secure a lasting peace, the threat posed by Iran to the United States and our Armed Forces remains significant."
The situation has drawn concern across Europe, where allies have watched the escalation with unease. The war has already strained transatlantic relations, with Trump threatening troop cuts in Spain and Italy over disputes related to the conflict. In a separate development, Trump ordered 5,000 US troops out of Germany, deepening the rift with Berlin. These moves have fueled debate in European capitals about the reliability of the US as a security partner and the need for greater European strategic autonomy.
Trump's letter also hints at ongoing diplomatic efforts. He indicated that negotiations have continued by phone after he called off his envoys' trip to Pakistan last week, where in-person talks had broken down. The president expressed dissatisfaction with Iran's latest truce proposal, delivered via Pakistani mediators, citing "things I can't agree to." He described Iran's leadership as "very disjointed," adding, "They all want to make a deal, but they're all messed up."
The economic impact of the conflict has been severe, particularly for Iran. The Iranian rial has hit record lows as Trump vows to maintain the naval blockade, exacerbating the country's financial crisis. Meanwhile, the US has imposed new sanctions, and Trump has even joked about seizing Cuba after Iran, though such remarks are widely seen as rhetorical.
For European observers, the episode raises fundamental questions about the future of international law and the role of Congress in authorizing military action. The Trump administration's willingness to bypass legislative oversight sets a precedent that could embolden other leaders to act unilaterally. As the situation evolves, European policymakers will be watching closely, particularly given the potential for spillover effects on regional stability and energy markets.
