“Gulf states, already uneasy, have been forced into a strategic dilemma.” Pierre Pahlavi Full Professor, Chair of the Department of Security and International Affairs, and Deputy Director in the Department of Defence Studies at the Canadian Forces College in Toronto

The temptation in moments like this is to measure escalation by visible firepower: missile ranges, troop movements, the opening—or avoidance—of a second front in Lebanon. But the most dangerous phase of this crisis may not be geographic expansion. It may be structural destabilization.

Much of the coverage treats the conflict as a conventional military exchange between Israel, the United States, and Iran. That framing misses two critical dynamics.

First, Iran was never designed to win a conventional war against a superpower. Its doctrine is asymmetrical. Ballistic missiles reaching 2,000 kilometres make for dramatic headlines, but Tehran’s real leverage lies in calibrated disruption: cyber operations, maritime insecurity in the Gulf, proxy ambiguity, and energy market shockwaves. If escalation comes, it is more likely to unfold in the grey zone than through a direct strike on North America.

Second, there is a growing risk of horizontal escalation—drawing in regional actors not because they seek war but because they are within range. Gulf states, already uneasy, have been forced into a strategic dilemma. European allies providing defensive support may find themselves redefined as co-belligerents. An expanding coalition changes the conflict’s logic. It dilutes pressure on Tehran in one sense—but also raises the stakes for everyone.

What concerns me most is not immediate regime collapse in Iran, nor a sudden regional war, but a grinding destabilization: energy volatility, cyber disruption, miscalculation among overstretched militaries, and a public debate fixated on spectacle rather than systemic risk.

The question is not how far missiles can fly. It is how far instability can spread—and how quickly.
