Israeli defense forces expanded ground operations in southern Lebanon while striking Iranian infrastructure to weaken Hezbollah. Actors United States: Shifted from defensive posturing to offensive strikes targeting Iranian infrastructure and military assets. Iran: Rejected diplomatic solutions and launched retaliatory missile attacks against Tel Aviv and US Gulf assets. Israel: Conducted a coordinated long-term campaign expanding ground operations in Lebanon and striking Iranian targets.

Economic Impact Brent crude prices surged nearly eight percent to $109 per barrel as traders priced in a prolonged closure of the Strait of Hormuz.
