The US and Israel finally decided to cross a Rubicon that had been looming over the Middle Eastern strategic landscape for some time. Their coordinated strikes on Iranian targets were not merely tactical operations; they were a political statement about deterrence and credibility while underlining the limits of diplomacy in a polarised geostrategic landscape.

Israel’s ‘Roaring Lion’ and US’s ‘Epic Fury’ were crafted as instruments of coercive diplomacy by other means, aimed at degrading Iran’s nuclear and missile infrastructure while reasserting a fraying regional order. With unconfirmed reports that the Iranian supreme leader, Ayatollah Ali Khamenei, may have succumbed, both sides have entered a point of no return.

US President Trump framed the strikes as “major combat operations” against “imminent threats,” underscoring US’s shift toward muscular unilateralism. Israeli PM Netanyahu situated the assault within its long-standing doctrine of preemption, arguing that an Iran on the cusp of nuclear capability constitutes an existential challenge that cannot be managed, only neutralised.

The convergence of American maximalism and Israeli insecurity has produced a moment of decisive escalation. At the heart of the crisis lies Iran’s nuclear trajectory. The June 2025 US-Israeli strikes had damaged facilities but failed to eliminate Tehran’s capacity to regenerate. Reports of covert rebuilding and IAEA’s concerns reinforced suspicions that Iran was edging closer to weapons-grade enrichment.

The US’s insistence on zero enrichment and the dismantling of facilities proved incompatible with Tehran’s red lines. The collapse of the Geneva talks was less a diplomatic accident and more the culmination of irreconcilable strategic aims.

The nuclear dimension, even though central, is not the only variable here. Israel’s security calculus has been shaped by Iran’s ballistic missile arsenal and its network of proxies, even if Hezbollah and Hamas have been degraded and Syria’s Assad regime has fallen. For Israel, the prospect of Iran crossing the nuclear threshold—even symbolically—would irreversibly alter the regional balance. Months of joint planning with the US reflect a shared assessment: deterrence, once eroded, must be restored dramatically.

Trump’s ‘maximum pressure 2.0’ policy has provided the broader scaffolding. After setbacks in 2024 that appeared to embolden Iran’s so-called ‘Axis of Resistance’, the US has sought to reclaim regional initiative. Military deployments since Jan 2026 were both signalling devices and operational preparation.

The strikes thus blended preventive logic with alliance management and reputational stakes.

Since Dec 2025, widespread protests fuelled by economic collapse and harsh repression have exposed fissures within Iran. Trump’s rhetoric urging Iranians to “take over your govt” has injected an overt regime-change undertone. While external force rarely produces orderly political transitions, the perception of regime vulnerability and the seduction of the idea of regime change may have narrowed the window for action in the US and Israel.

The regional implications are immediate and combustible. Iranian retaliation against Israel and US bases in the region signals that escalation is no longer hypothetical but unfolding. Proxies in Iraq and Yemen have hinted at sustained attrition, even if their capabilities are diminished. The Strait of Hormuz, the world’s most sensitive energy choke point, now sits at the epicentre of strategic anxiety. Gulf states hosting US assets face the unenviable task of balancing deterrence with de-escalation.

The humanitarian and political consequences could be profound. Civilian casualties, infrastructure damage and displacement risk deepening societal fractures. A weakened clerical establishment might confront intensified internal unrest, potentially reshaping alignments—consolidating Israel’s ties with Sunni Arab states while fragmenting Shia influence. Saudi has expressed full solidarity with those targeted nations and pledged to provide “all its resources” and “all its capabilities” to support them in any measures they take even while making clear that it would not allow its airspace or territory to be used for strikes on Iran. But a protracted conflict could just as easily destabilise Lebanon and Iraq, compounding an already fragile regional order.

Globally, the shockwaves are evident in energy markets. Oil price volatility threatens to exacerbate inflationary pressures and slow growth in Europe and Asia. Russia and China, both invested in Iran strategically and economically, have condemned the strikes, but have limited means to assert themselves. The episode also tests the resilience of nuclear non-proliferation norms. Equally significant is what this moment reveals about American statecraft.

The willingness to privilege force over multilateral and diplomatic consensus reflects a recalibration of US grand strategy. Legal debates over pre-emption and sovereignty will persist, but the message is unmistakable: the US is now prepared to act decisively when it judges the balance tilting away. The latest conflagration is the product of accumulated mistrust, failed diplomacy and strategic impatience. Israel and the US may succeed in degrading Iran’s capabilities and reasserting deterrence. But retaliation already underway underscores the inherent volatility of coercive gambits in a crowded geopolitical theatre.

The Middle East finds itself, once again, at a deeply precarious strategic crossroads and the international community, such as it exists, confronts a familiar yet formidable challenge: how to prevent a calculated strike from cascading into a conflagration whose costs—human, economic and strategic—would far exceed the gains sought.
