Old And New Gulf Faultlines Exposed By Iran War

Saudi Arabia is the largest and richest country in the Gulf. But many of its transformative economic projects require political stability and a high oil price to succeed.

The war has exposed the limits of its policy of tentative outreach to Iran, and of its partnership with a US that is so closely allied with Israel. So, the Saudis have strengthened defense ties with nuclear-armed Pakistan.

These deepening ties have been met with dismay in the UAE, which has close ties to India. The Emiratis have been critical of Pakistan during the war, calling on Islamabad to condemn the Iranians more forcefully – something that is not possible due to Pakistan's role as a mediator in peace negotiations.

At least partly in frustration at its response to the war, the UAE recently demanded that Pakistan repay a US$3.5 billion loan. Saudi Arabia immediately came to Pakistan's rescue by providing financial support.

The UAE's announcement to leave OPEC coincided with a meeting of the Gulf Cooperation Council in the Saudi Arabian capital Riyadh, where members sought to find common ground on the Iran war. This was a major affront to the Saudis.

The war has sparked other frictions in the Gulf, including reviving old tensions between the UAE and Iran over three islands – Abu Musa, Greater Tunb and Lesser Tunb – that Iran occupied at the time of Emirati independence from Britain in 1971. These islands strengthen Iran's strategic position along Gulf shipping lanes.

The UAE has long claimed sovereignty over the islands, while Iran claims they were always part of its territory. Iran's control of the three islands is thought to be part of a secret deal between Britain and the Shah of Iran around 1970, whereby the shah would renounce a claim Iran maintained to Bahrain in return for the islands.

This and other historic border disputes in the region, including between the UAE, Saudi Arabia and Oman, remain some of the most sensitive topics in modern Gulf history. For a forthcoming book on the rise of the Gulf states, I have tried to access relevant UK Foreign Office documents, but have had numerous freedom-of-information requests denied on closed material dating back to the 1960s and earlier.

The northern Gulf state of Kuwait has also been hit hard during the conflict. Here, many attacks seem to have come from Shia militias based in Iraq. These attacks have revived traumatic memories of Iran-linked political violence in the 1980s, and Iraq's invasion in 1990.
