Frequently Asked Questions
How long will the Iran war last?
The most likely scenario (35% probability) is a limited engagement lasting 2-3 months, with a negotiated ceasefire after achieving key military objectives. The best-case scenario is a 2-4 week air campaign (25% probability).
What would end the war?
Key pathways to resolution: negotiated ceasefire through China/Russia mediation, Iranian agreement to nuclear inspections regime, UN Security Council resolution, or mutual exhaustion. A complete Iranian regime change is unlikely without ground forces.
Is a ceasefire possible?
Yes. China has offered to mediate, and back-channel diplomatic contacts continue. Historical precedent (1988 Iran-Iraq ceasefire) suggests both sides may accept a face-saving diplomatic solution after initial military objectives are met.
Will there be a ground invasion of Iran?
A full-scale ground invasion is considered unlikely (15% probability). Iran has 610,000 active military personnel and challenging mountainous terrain. The US strategy appears focused on air and naval operations with limited special forces.
