US–Iran War Drags Into Protracted Air and Naval Campaign With No Clear Exit

Risk direction: escalatory · Impact: CRITICAL
Full prediction
Over the next 30 days, the US–Iran conflict is likely to remain an active air and naval campaign characterized by periodic Iranian drone and missile strikes on US bases and Gulf infrastructure, and US counterstrikes, but without a decisive ground invasion or negotiated ceasefire. The war’s munitions burn, already at $43.6B in US spending and forcing five‑year resupply delays, will deepen strain on NATO arsenals and further limit Western capacity to support Ukraine and deter Russia and China. Strategically, this normalizes simultaneous multi‑theater confrontation and raises global accident and miscalculation risk, particularly if AI‑driven targeting errors recur. Confirmation would be continued kinetic exchanges, sustained Hormuz disruption, and no serious ceasefire talks; denial would be a surprise US–Iran framework around de‑escalation or a dramatic regime‑change event in Tehran.
