At the close of the G7 summit in Évian-les-Bains, France, President Donald Trump mounted a robust defence of the interim agreement struck with Iran, framing it as a necessary bulwark against a global economic meltdown. "The one thing I didn't want to see is, I didn't want to see economic catastrophe," Trump told reporters, warning that a prolonged Middle Eastern conflict would have sent energy prices spiralling and disrupted key shipping routes indefinitely. He invoked the spectre of Herbert Hoover, the American president who presided over the 1929 stock market crash, to underscore the stakes of inaction. The remarks, carried by news outlets from Mumbai to Mexico City, signalled a concerted effort to sell the deal to a sceptical international audience.

The contours of the agreement, described by Trump as a "historic" memorandum of understanding, extend well beyond a simple ceasefire. According to briefings in Évian, Iran is required to surrender its stockpile of enriched uranium, a concession that Washington insists will erect "a wall against the nuclear weapon." The pact also aims to fully reopen the Strait of Hormuz, the chokepoint through which roughly a fifth of the world's oil passes, and to end the current hostilities. In a striking claim reported by Spanish media, Trump asserted the deal had effectively achieved "regime change" in Tehran — a statement that went beyond the official communiqués and raised eyebrows among European diplomats. Brazilian coverage noted that Iran could gain access to a $300 billion fund only if it "behaves," hinting at the conditional financial relief embedded in the accord.

Viewed from Washington, the agreement represents a high-stakes gamble to neutralise a foreign policy crisis that threatened to define Trump's presidency. European allies, while publicly welcoming the de-escalation, remain privately cautious, scarred by the collapse of the 2015 nuclear pact and wary of Tehran's compliance. In the Middle East, the deal's promise to unlock frozen Iranian assets is tempered by deep mistrust; analysts in London note that the "behave" clause suggests a mechanism for reimposing penalties, leaving Iran's economic lifeline vulnerable to political whims. For emerging economies such as India and Brazil, the mere prospect of stabilised crude prices and secure maritime passage offers a respite from inflationary pressures that had rippled across the Global South.

Yet the path from interim understanding to durable peace is strewn with obstacles. The memorandum must be translated into a binding document, possibly within days, but verification of uranium handover and the scope of sanctions relief remain contentious. Trump's reference to having "taken a lot of money" from Iran and needing to return it "at some point" underscores the financial complexities ahead. Moreover, the president's assertion of regime change — whether rhetorical flourish or policy goal — risks hardening positions in Tehran and alarming Gulf allies who fear a rehabilitated Iran. As global markets watch for concrete steps, the Évian declaration stands as a fragile but significant pivot, one that may avert immediate economic shock but leaves the broader architecture of Middle Eastern security still to be built.
