United Arab Emirates

So what?  Losing the Dubai conduit on top of a threatened global secondary-sanctions dragnet pushes Iran toward its thinner remaining channels — Central Asian and Iraqi intermediaries — which are easier to monitor but also more prone to overflow into new smuggling routes as displaced trade looks for a way through. Expect sanctions-screening and trade-compliance workloads tied to Iran-adjacent shipments to rise sharply in the coming weeks as banks and ports move to avoid secondary exposure.

So what?  Dubai supplies roughly a third of Iran's annual imports, more than China or Turkey, so a full Emirati trade halt is the kind of pressure Tehran has genuine incentive to defuse quietly even while denying responsibility in public. Don't read Aramco's partial resumption as a broader thaw: a fourth Gulf economy now in open economic confrontation with Iran raises the odds Tehran leans harder on the Hormuz blockade rather than easing it, keeping diversion and compliance costs elevated for any cargo still routing through the strait.
