Iran could strike US targets across the Middle East – such as special forces camps in Iraq, military bases in the Gulf, and diplomatic missions in the region. Iran's proxy forces - Hamas and Hezbollah – may be much diminished but its supportive militias in Iraq remain armed and intact.

Israel attacked Iran early Friday and killed many of the country’s top military leaders and scientists. Iran retaliated with missiles and drones.

Before Israel launched a wave of strikes against Iran’s nuclear facilities and top military leaders this week, its spies were already on the ground in enemy territory.
