Quick Summary

A report by the International Institute for Strategic Studies suggests that Gulf states need to reconsider their trillion-dollar defence strategies due to economic strain and doubts about the continued value of US military bases during a potential conflict with Iran. The study highlights that before an 8 April ceasefire, regional states faced over 4,670 Iranian drones and more than 1,400 ballistic missiles, causing significant damage estimated at up to $58 billion. It also notes that despite substantial investment in US weapons systems, Gulf militaries are unprepared for the new type of warfare they face, with a heavy reliance on US defence systems and limited retaliatory options.

Story summary

As of October 30, 2026, a report by the International Institute for Strategic Studies suggests that Gulf states need to reconsider their trillion-dollar defense strategies in light of recent conflicts with Iran, particularly given the reliance on US-supplied weapons. The report identifies significant shortcomings, including an over-reliance on US armaments and inadequate regional military integration. During the weeks preceding a ceasefire on April 8, these states faced approximately 4,670 Iranian drones and over 1,400 ballistic missiles, with nearly half targeting the United Arab Emirates. Although most attacks were repelled, damage to energy infrastructure was estimated at up to $58 billion (£43 billion). The report warns that Iran would likely see any reduction or withdrawal of US forces from the Gulf as a strategic success and use it to criticize the reliance on American protection by these states.

Narrative

Despite huge investment in mainly US armaments, the report identified significant shortcomings: “overwhelming reliance on US-supplied air- and missile-defence systems and munitions; a failure to achieve regional defence integration; a shortage of minesweeping capability; limited retaliatory options; and the prohibitive costs stemming from an over-dependence on expensive, high-end systems to take down relatively inexpensive drones and missiles”.

Claims (15 extracted, 2 hedged)

Gulf states are going to have to reconfigure their trillion-dollar defences given the damage inflicted on their economies and the questionable continued value of US bases in the face of Iranian attack, according to a study by the International Institute for Strategic Studies. uncertain
states → go → Studies
The report says that in the weeks before the 8 April ceasefire, 12 regional states, overwhelmingly in the Gulf, faced 4,670 Iranian one-way attack drones and more than 1,400 ballistic missiles. asserted
states → say → drones
Nearly half were aimed at the United Arab Emirates. asserted
half → aim → Emirates
Although the vast majority were repelled, one estimate of the damage to energy infrastructure cited by the report is put as high as $58bn (£43bn). asserted
estimate → repel → 58bn
Iran would portray either a reduction or complete withdrawal of US forces from the Gulf region as “a strategic success and vindication of its steadfastness, but also use it to embarrass the Gulf states about their decades-long courtship of US protection”. asserted
Iran → portray → protection
The report says the war also highlights another “uncomfortable truth for the Gulf states: not only has their trillion-dollar acquisition of US weapons not translated into US protection at the crucial time, but their respective militaries are also not adequately prepared for the new kind of attritional air war to which they are being exposed”. asserted

Despite huge investment in mainly US armaments, the report identified significant shortcomings: “overwhelming reliance on US-supplied air- and missile-defence systems and munitions; a failure to achieve regional defence integration; a shortage of minesweeping capability; limited retaliatory options; and the prohibitive costs stemming from an over-dependence on expensive, high-end systems to take down relatively inexpensive drones and missiles”. asserted
report → identify → drones
The report is neutral on whether the divided Gulf states should seek a new non-aggression pact with Iran, but notes that the US-Iran war has shown that longstanding defence and security partnerships with the US “have failed to ensure adequate protection against Iranian aggression … “If anything, US military bases and defence partnerships with the US have provided Iran with another pretext for attacks against the Gulf states. asserted
bases → divide → states
Public opinion on the US in the Gulf has also been shifting, “from security provider to strategic liability”. asserted
opinion → shift → liability
Any reduction or withdrawal of US forces from the Gulf region would be portrayed by Iran “as a strategic success and vindication of its steadfastness” and would also be used “to embarrass the Gulf states about their decades long courtship of US protection,” the report notes. asserted
report → portray → protection
The study comes after Chris Murphy, the Democrat senator and member of the senate foreign relations committee, said a live debate was under way in the US military about the value of seeking to rebuild the damaged US bases in the Gulf. asserted
debate → come → Gulf
He said the Gulf state leadership “want us to rebuild” and “to keep a presence in the region”, but said: “What good is it to have a base in the region to protect American interests if within 24 hours of a hot war starting, it is wiped off the map? asserted
it → say → map
“We would be criminally incompetent as stewards of taxpayer dollars if we were to rebuild bases that are blown up within hours of the next war starting. asserted
war → rebuild → hours
“So clearly, we are going to have to have a smaller footprint in the region, and the limiting principle on the footprint that we rebuild will be ‘What can we protect?’ because we clearly cannot protect the scope of our footprint today and if we can’t protect it, it is useless.” asserted
it → go → it
He suggested that, at the very least, the US may need to relocate its bases in the eastern Mediterranean further away from Iranian missiles. uncertain
US → suggest → missiles
