Gulf states will have to reconfigure their trillion-dollar defenses given the damage to their economies and the questionable value of US bases in the face of Iranian attack, according to a study by the International Institute for Strategic Studies (IISS) reported by the Guardian.

The report cites 4,670 Iranian one-way attack drones and more than 1,400 Iranian ballistic missiles against 12 regional states in the weeks before the April 8 ceasefire, and an estimate cited in the study puts damage to energy infrastructure at as much as US$58 billion.
