The Pentagon is exploring a total withdrawal of forces from its military bases in Saudi Arabia and Kuwait after a series of Iranian drone and missile attacks destroyed hundreds of structures across the region. Defense officials are reviewing their footprint in the Gulf following an Associated Press analysis that identified more than 115 Iranian strikes on over two dozen U.S. installations. The AP found that Iran’s updated tactics focused on destroying radars and aircraft hangars first to neutralize defenses, which then enabled subsequent strikes on warehouses and troop barracks.

Internal Pentagon estimates price the cost of damage to these facilities at between $5B and $15B, which is separate from a reviewed document that placed the total cost of the Iran war at $47.1B as of Oct 16. A Wall Street Journal investigation identified 274 damaged buildings at 24 sites across seven countries, including Iraq, Qatar, and the UAE, with the Fifth Fleet’s base in Bahrain largely evacuated. More than 20 U.S. service members were killed and over 400 wounded in war-related activity before the government ceased reporting war-specific casualty figures in July.
