US-Iran War SITREP: Ground Prep and Missile Escalation — March 20, 2026

The US-Iran conflict, now entering its fourth week, has escalated into a multi-front confrontation involving direct strikes between US-Israeli forces and Iranian proxies, with significant impacts on regional stability and global energy markets. US President Trump has declared victory over Iran's navy, air force, and defenses, while reinforcing Marine Expeditionary Units (MEUs) in the region and preparing contingency plans for ground troop deployments into Iran. Iranian leadership, led by Supreme Leader Khamenei, remains defiant, continuing missile launches against Israeli targets and asserting the regime's survival amid targeted assassinations of key officials. The effective closure of the Strait of Hormuz has triggered force majeure declarations in Iraq and halted energy exports, exacerbating inflation and supply chain disruptions worldwide. Allied dynamics are shifting, with the UK authorizing US use of bases for strikes on Iranian missile sites, while Saudi Arabia and UAE edge toward greater support. Proxy actions in Iraq and Lebanon intensify, with drone strikes on US bases and IDF advances in southern Lebanon resulting in heavy casualties. Economic fallout includes surging US inflation expectations to 5.2%, UK bond yields above 5%, and threats to global food supplies due to disrupted fertilizer shipments. Despite Trump's signals of de-escalation, no ceasefire is in sight, and Iranian retaliation targets extend to Gulf states and Israeli civilian areas.
