Full prediction
Over the next 30 days, the current U.S.–Iran confrontation is likely to evolve into a broader shadow war spanning Gulf waters, Iraq, Syria, and possibly Yemen, featuring proxy rocket attacks, drone strikes, and maritime harassment rather than open-state warfare. Iran will leverage aligned militias to hit U.S. and partner assets at plausible deniability, while Washington intensifies interdictions of Iranian-linked shipping and strikes on proxy targets. This pattern will normalize higher operational risk across multiple theaters, drain U.S. ISR and missile-defense inventories, and inject chronic instability into energy corridors. Confirmation: a sustained tempo of proxy attacks and interdictions without a formal ceasefire; denial: a negotiated de-escalation framework or backchannel deal limiting actions to maritime signaling only.
