Iran’s proxy fighters in neighboring Shiite-majority Iraq and elsewhere pose a formidable ground threat to American military and diplomatic outposts, Mr. Abdel Ghafar said. And it would take only three or four minutes for a ballistic missile fired from Iran to hit bases in Gulf countries housing U.S. troops, he said.

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.
