US–Iran Naval Standoff Settles Into High-Tempo Shadow War in Hormuz

Full prediction
Within seven days, the US–Iran confrontation in the Strait of Hormuz is likely to evolve into a pattern of frequent non-lethal harassment, drone interceptions, and sabotage attempts on unmanned systems, falling short of direct attacks on crewed warships or commercial tankers. Both sides will test each other's red lines using drones, cyber tools, and proxies while publicly accusing the other of escalation. This "shadow war" raises the baseline risk of an accident or misread escalation, and will force navies and shippers to revise rules of engagement and routing patterns. Confirmation would be multiple additional incidents involving drones or unmanned vessels and sustained rhetorical clashes without tanker strikes; denial would be either a formal de-escalation mechanism or a sudden leap to tanker or warship attacks.
