Saudi Arabia is facing a difficult dilemma. Ever since the US and Israel launched their war on Iran on 28 February, the Saudis have largely tried to stay out of it.
But now, after being attacked from three sides, the Saudis have had enough. This week, they carried out joint strikes with the US on Iranian proxy militias in Iraq who they believe have been launching drones at the Kingdom.
For Saudi Arabia the dilemma now is whether to keep on hitting back as a deterrent, or whether to try to de-escalate the situation, perhaps by paying off some of their adversaries.
So who is attacking who and why?
First, a bit of context. There are broadly two sides in the conflict that has been consuming the Gulf and other parts of the Middle East for five months now.
On one side there is Iran and its Islamic Revolutionary Guards Corps (IRGC). Allied to them are the Houthis in Yemen, a tribal group who took over much of the country in 2014.
Also backed by Iran are the Popular Mobilisation Forces in Iraq, the paramilitary group that has allegedly carried out 30 drone strikes on Saudi Arabia and has now been attacked in return.
Then there is Hezbollah in Lebanon, still a potent force but one that is currently lying low.
On the opposite side of this conflict is the US with its immensely powerful Central Command (Centcom) forces plus – to varying degrees – the Gulf Arab states and Jordan. Israel remains a close US ally but is currently not an active participant in this war.
Iran has most recently been concentrating its drone and missile attacks on Jordan, Kuwait and Bahrain, as well as targeting any commercial shipping that tries to slip through the Strait of Hormuz while avoiding Iran’s new rules and routing.
The addition of Iraqi militias and the Houthis in Yemen is a relatively new phenomenon and it shows how – without a lasting peace deal between the US and Iran – the region risks becoming ever more embroiled in a widening conflict.
There are a number of reasons why Saudi Arabia is trying not to get sucked into a full-scale conflict.
Its de facto ruler, the relatively young Crown Prince Mohammed Bin Salman, has embarked the country on a course known as “Vision 2030”.
His aim is to diversify the Kingdom away from its dependence on oil revenues and create vibrant, modern, domestic industries that will provide meaningful jobs for the hundreds of thousands of graduates and school leavers pouring onto the job market each year.
Part of Vision 2030 involves attracting foreign investment. Part of it also involves building things like data centres that are vulnerable to attack.
This is not going to work if Saudi Arabia finds itself under an enduring, long-term threat from drones fired across its southern border by the Houthis in Yemen or ballistic missiles fired directly by Iran.
Back in September 2019, the Saudis suffered an unpleasant shock.
With relations with Iran in a poor state, the Saudis woke up to find that an Iranian proxy militia in Iraq had launched a fleet of drones at two of its most vital oil facilities, at Abqaiq and Khurais.
At the time there was a suggestion that the attack had come from the Houthis in Yemen but I visited the site straight afterwards and I could clearly see the holes in the superstructures all facing northwards.
That attack knocked half of Saudi oil exports offline for several days and it was a wake-up call to Riyadh as to just how vulnerable its critical national infrastructure is to attack.
On Monday, satellite images showed the Abqaiq oil facility was struck by drones launched once again by Iranian proxy militias in Iraq.
Then there is oil, still the lifeblood of the Saudi economy.
Iran retaliated against US and Israeli attacks in February by effectively closing off the Strait of Hormuz, a critical shipping channel between Iran and the Gulf through which 20% of the world’s oil and liquified natural gas travelled.
In response, the Saudis pumped as much oil as they could – around five million barrels per day – through their east-west pipeline to their export terminal on the Red Sea, on their opposite coast, at Yanbu.
From there it was loaded onto tankers that headed south, out into the Arabian Sea and off to markets in Asia.
