In a striking disclosure that lays bare the fissures in American foreign policy, former Secretary of State John Kerry has revealed that Donald Trump was the sole US president to assent to Israeli Prime Minister Benjamin Netanyahu's proposals for military action against Iran. This account, delivered during a televised interview, positions the Trump administration as a stark outlier, diverging from a cautious consensus maintained across multiple presidencies. The revelation immediately reframes historical understanding of US-Israel coordination on Iran, suggesting a momentary convergence that prior leaders had deliberately avoided.

From Washington's perspective, the repeated rejections by Presidents George W. Bush, Barack Obama, and Joe Biden underscored a entrenched institutional doctrine: military force remains a last resort only after diplomatic avenues are fully exhausted. Kerry, who participated in those deliberations, emphasised that each administration judged the peaceful process not yet spent, thereby denying Netanyahu the crucial American backing he sought. This continuity across both Republican and Democratic tenures had previously signalled a measured, if often strained, approach to managing the Iranian threat, prioritising containment and negotiation over open conflict.

Viewed from European capitals, particularly London, Mr Trump's acquiescence is interpreted as a profound shift away from transatlantic foreign policy norms, aligning with his administration's broader propensity for unilateral gestures. Analysts note that this move likely fortified Netanyahu's domestic position while unsettling allies committed to the Joint Comprehensive Plan of Action. From the Middle East, the disclosure reinforces Tehran's narrative of American-Israeli belligerence, potentially calcifying its stance in any renewed nuclear talks and complicating regional de-escalation efforts.

Kerry, invoking his experience as a Vietnam veteran, framed the decision within a sombre historical context, drawing direct parallels to the conflicts in Vietnam and Iraq. He warned of the grave human costs and the dangers of misleading the public—cautionary tales he implied were disregarded in the Trump administration's calculus. This admonition serves as a pointed critique of the readiness to bypass diplomatic exhaustion for military expediency.

Looking forward, this episode casts a long shadow over US-Iran policy and the Atlantic alliance. With the Biden administration recommitted to diplomatic engagement, the revelation highlights the volatile pendulum swings in American strategy. The enduring implication is whether Trump's temporary alignment has irrevocably shifted Israel's expectations of US support, thereby undermining future efforts to stabilise the region through sustained dialogue and multilateral frameworks.
