Side-by-side comparison: Iran War (2026) vs Iraq War (2003). Daily cost: $891M vs $720M. Oil impact: Hormuz 21% of global supply vs Iraq 3%. Troops: 45,000 vs 150,000+. Shipping disruption: 170+ vessels trapped vs minimal. Key difference: Iran controls the world's most critical oil chokepoint.
The Iraq War cost $2.4 trillion over 8 years ($720M/day adjusted for inflation). The Iran War costs $891M/day — more expensive per day, but total cost depends on duration.
Critical difference: Iran controls the Strait of Hormuz (21% of global oil). Iraq War affected only 3% of global supply. Hormuz closure has 7x the oil market impact.
In terms of global economic impact, yes. The Iran War affects 21% of global oil supply, global shipping routes, and 30+ countries. The Iraq War was more localized in its economic effects.
Unlikely. Experts project 3 weeks to 12 months. Iraq was expected to be short but lasted 8+ years due to occupation. Iran has no occupation plan, reducing risk of prolonged conflict.
