From London: As Australians woke this week to the familiar rhythms of a late-summer morning, a consequential debate was taking shape inside the White House about one of the most dangerous foreign policy questions of our time: what to do about Iran.
The Trump administration, according to reporting by the Sydney Morning Herald, has been presented with six distinct options for confronting Tehran's nuclear ambitions and its support for regional militias. They range from a return to diplomatic engagement, potentially including a revised nuclear agreement, through to direct military strikes on Iranian nuclear infrastructure. Between those poles lie graduated sanctions packages, covert action, support for internal dissent, and a strategy of sustained proxy pressure designed to bleed the regime without triggering open war.
Each option carries its own logic. And each carries its own dangers.
The Military Temptation
Trump has demonstrated in his second term that he is willing to use military force quickly and with limited public deliberation. The strike that killed Hamas political leadership earlier this year, and the sustained pressure campaign against Houthi positions in Yemen, showed a president comfortable with decisive action. That appetite, as analysts in Washington and London have noted, is now being applied to the Iran question with fresh urgency.
The case for a military option is not frivolous. Iran's nuclear programme has advanced significantly since the collapse of the 2015 Joint Comprehensive Plan of Action, and the window for a non-nuclear Iran, if it ever existed, is narrowing. Proponents argue that only the credible threat of force, or force itself, can alter the calculus of a regime that has consistently interpreted restraint as weakness.
But the counterargument is equally serious. Iran is not a small or poorly defended state. Its nuclear sites are dispersed, hardened, and in some cases buried so deeply that conventional munitions cannot guarantee their destruction. A strike that fails to eliminate the programme would almost certainly accelerate it, as Iran's leadership would have every incentive to race toward a deterrent capability. And the regional response could be severe: Hezbollah in Lebanon, the Houthis in Yemen, and Iranian-aligned militias in Iraq all possess the means to strike at US forces, Israeli cities, and Gulf oil infrastructure simultaneously.
The Diplomatic Path and Its Sceptics
A negotiated settlement, perhaps the option most foreign policy establishments in Europe and Australia would prefer, is theoretically still available. The Islamic Republic has never formally declared itself a nuclear weapons state, and its supreme leader has at various points issued religious edicts against nuclear weapons, though the credibility of those declarations is widely disputed.
The International Atomic Energy Agency has continued to document Iran's enrichment activities, and its reports provide the clearest independent picture of where the programme stands. That transparency, limited as it is, at least creates a foundation for talks.
European governments, particularly the UK, France, and Germany (the so-called E3), have spent years trying to preserve diplomatic channels. Their position, as articulated repeatedly through the European Council, is that a negotiated cap on enrichment is preferable to any military outcome, even an imperfect agreement. They have watched with concern as Washington's appetite for that approach has fluctuated wildly between administrations.
The sceptics, and there are many, point out that Iran has used previous rounds of negotiation primarily to buy time. They argue that the regime's behaviour in Lebanon, Gaza, and Yemen reveals a strategic intent that no arms control agreement will fundamentally alter. That critique deserves fair hearing: it is not mere hawkishness but a reading of two decades of evidence.
What Australia Has at Stake
For Canberra, the implications are real even if Iran sits far from Australia's immediate neighbourhood. Global oil markets are acutely sensitive to Middle East instability. A conflict that disrupts Gulf shipping lanes or damages Saudi and Emirati export infrastructure would send energy prices sharply higher, compounding the cost-of-living pressures already weighing on Australian households.
Australia's alliance with the United States also means that any major military action in the region creates expectations of at least political solidarity, if not operational participation. The Department of Foreign Affairs and Trade has historically been cautious about Middle East entanglements that do not directly implicate Australian security interests, and that caution has broad bipartisan support domestically.
There is also the question of what a destabilised Iran means for the broader non-proliferation order. If Tehran acquires a nuclear weapon, the pressure on Saudi Arabia, Turkey, and potentially others to follow suit would intensify. A Middle East with multiple nuclear-armed states would present profound challenges for global security architecture, including the treaties and norms that underpin Australia's own security calculations under Australia's defence posture.
No Clean Options
The honest assessment, from this vantage point in London where European governments are watching Washington with unconcealed anxiety, is that none of the six options available to Trump is clean. Diplomacy requires a partner willing to deal in good faith. Sanctions have been in place for years without halting enrichment. Covert action and support for internal dissent are slow and uncertain. Military strikes risk catastrophic escalation. Doing nothing risks a nuclear-armed Iran.
What the situation demands is something that does not come naturally to the current political climate in Washington or anywhere else: sustained strategic patience combined with credible pressure, held consistently over time, and coordinated with allies who each bring different leverage and different vulnerabilities to the table.
Reasonable people genuinely disagree about which combination of these options gives the best chance of a stable outcome. The debate is not between hawks who want war and doves who want peace; it is between people who weigh the risks differently and who read Iran's intentions through different historical lenses. That complexity deserves honest acknowledgement, even as the pressure for a simple answer grows.
