Full prediction
Over the next 30 days, the US–Iran conflict is likely to solidify into a protracted shadow war centered on maritime, air, and cyber operations in and around the Gulf, with persistent but managed kinetic exchanges. Iran will lean on proxy UAV and missile campaigns (including via Houthis) while probing US naval formations and Gulf infrastructure, and Washington will respond with targeted strikes, interdictions, and cyber operations to sustain the blockade and reassure partners. Full‑scale invasion or mass bombing campaigns are less likely than an exhausting, resource‑intensive low‑to‑medium intensity conflict. Confirmation would be continuous, though not all‑out, skirmishes, periodic tanker incidents, and ongoing drone/missile exchanges without a decisive ceasefire; denial would be either a major peace framework or a sudden, large‑scale air campaign that radically changes the conflict’s character.
