The war involving Iran, the United States and Israel has entered a more dangerous phase, defined less by decisive victories than by expanding reach, blurred accountability and mounting global costs. Events over the past 48 hours, from the Gulf to the Indian Ocean, suggest a conflict that is no longer contained geographically, militarily or economically.
A battlefield without clear front lines
In Bahrain, the war’s ambiguity is on display. A March 9 explosion that injured more than 30 civilians in a residential area was initially attributed to an Iranian drone strike. But subsequent analysis indicates the blast may have been caused by a Patriot interceptor, likely fired by a US-operated system, rather than the incoming threat it was meant to destroy.
Bahrain maintains the system successfully intercepted a hostile drone, underscoring a broader problem: in dense urban environments, even defensive systems can inflict civilian harm. The distinction between attack and interception is becoming harder to sustain politically, even if it remains technically meaningful.
At the same time, Iran is extending the war’s geographic scope. Its launch of two long-range ballistic missiles at the US-UK base on Diego Garcia, roughly 4,000km away, marks its most ambitious strike yet. Neither missile hit the target, one failed mid-flight and the other was intercepted, but the message was clear.
Tehran has demonstrated a capability that potentially places parts of Europe within range, alarming Western governments and complicating calculations about escalation. The strike also drew a sharp response from Britain, which condemned it as a reckless escalation while insisting it remains focused on defensive operations.
What Iran lacks in precision it is compensating for in reach and signalling. The war is no longer confined to the Middle East in any meaningful strategic sense.
Hormuz becomes the centre of gravity
If the battlefield is expanding, the economic stakes are tightening around a single chokepoint: the Strait of Hormuz. Iran’s effective closure of the waterway, through which roughly a fifth of global oil flows, has already pushed crude prices above $100 a barrel and disrupted shipping.
In response, Donald Trump has issued a 48-hour ultimatum demanding that Iran reopen the strait or face US strikes on its power infrastructure. Iran, for its part, has threatened retaliation against American and allied energy assets, raising the prospect of a broader campaign targeting critical infrastructure across the region.
This is economic warfare in its purest form. Neither side needs to defeat the other militarily to impose global costs. Disrupting energy flows is enough.
A conflict drifting towards escalation
The war, now in its fourth week, has already killed more than 2,000 people and triggered retaliatory strikes across energy facilities, military bases and urban areas. Israeli attacks on Iranian gas infrastructure and Iran’s counterstrikes on Gulf facilities have reinforced a pattern: escalation is no longer linear but systemic, spreading across sectors as well as borders.
What emerges is not a conventional war with clear fronts and objectives, but a networked conflict. Air-defence systems can cause civilian casualties. Missiles can miss but still reshape strategy. Shipping lanes can matter more than territory.
The risk is not just that the war intensifies, but that it continues to expand in unpredictable ways. Each move, whether a misfired interceptor or a symbolic long-range strike, adds another layer of uncertainty.
The uncomfortable reality is that escalation is no longer a single decision. It is becoming the default trajectory.
