Full prediction
Within 7 days, Iran’s IRGC Navy and aerospace units are likely to conduct limited missile or drone harassment of commercial or US-allied naval vessels near Hormuz—such as fly-bys, illumination by targeting radar, or near-miss missile tests—without immediately sinking a major ship. The aim will be to signal capability and resolve against Trump’s ownership claim while calibrating below a trigger threshold for full US retaliation. This matters because even non-lethal incidents can prompt convoy operations, new ROE, and a rapid militarization of shipping lanes, raising the odds that any later misstep becomes catastrophic. Confirmation would be credible reports of UAV swarms, close missile tests, or temporary seizures of smaller flagged ships; a contrarian path would see Iran restrain its forces while focusing instead on cyber or proxy pressure.
