Full prediction
Over the next 30 days, the Iran–U.S. confrontation is likely to solidify into a limited war characterized by recurring missile and drone salvos, targeted strikes on oil tankers and infrastructure, and persistent threats to U.S. bases—but without a U.S. ground invasion or Iranian attempt to close Hormuz completely. Both sides will aim to inflict strategic and economic pain while avoiding actions that would necessitate regime-change-level escalation. This will normalize high operating risks for maritime traffic, strain Western air-defense and naval resources, and tie regional partners more tightly to U.S. security guarantees. Confirmation would be repeated but bounded exchanges and continued shipping, albeit under heavy escort; any move to physically mine or blockade Hormuz or a major strike on U.S. homeland assets would mark a shift toward full-scale war.
