Seven years ago, I attended an International Energy Forum (IEF) meeting in Riyadh, Saudi Arabia, with some of the region's most senior diplomats.

The country's infrastructure is based on exporting oil. And its power in the world, including its historic power to run embargoes, is based almost entirely on oil being the world's dominant energy source. From that perspective, it's no surprise that the displacement of Saudi oil by Qatari and Iranian natural gas is causing many of the tensions in the Middle East today.

When the current state of Saudi Arabia was founded in 1932, natural gas was barely used as a fuel and represented a tiny fraction of the world's energy mix. For decades, when Saudis would extract natural gas while drilling for oil, they'd burn it off rather than sell it. However, today natural gas represents over 24 percent of the world's energy mix.

In other words, the central conflict in the Middle East today is not about religious differences between Sunnis and Shias. It is about money and the future of energy.

So what can the Saudis do? In terms of stopping the growth of renewables, not much, other than convincing the US to abandon the Paris Agreement, which Trump did shortly after his visit to the country.

Fracking in the US is also extremely difficult for Saudi hawks to stop. However, both American frackers and Saudi benefit from higher oil prices and the removal of competition (i.e. Qatar and Iran) for the European energy market.

Thus, from the perspective of Saudi hawks, the best strategy to boost the current value of Saudi oil would be to substantially reduce the flow of natural gas from Qatar and Iran to Europe, if not to the rest of the world. In order to significantly reduce natural gas exports to Europe, the Saudi hawks have three options:

Expand their naval forces or war in Yemen in order to disrupt or control the Bab Al Mandeb Strait (BAM) and/or chokepoints in the Red Sea, through which Qatar and Iran ship nearly all their natural gas to Europe;

Launch or threaten attacks on Qatar until natural gas extraction in the Persian Gulf is significantly reduced or redirected and sold to Saudi Arabia at a discount;

Increase the cost of shipping Qatari LNG to Europe by convincing the UAE to place a port embargo on Qatari/LNG vessels and/or by convincing the Egyptians to block or levy high taxes on Qatari/LNG vessels through the Suez.

Currently, hawks in Saudi Arabia are opting for the third option via a port embargo in the UAE. However, unless the Egyptians cut off the Suez Canal, it is unlikely that such an embargo will be sufficient to raise Qatari LNG shipping costs to a level where Saudi oil will regain its predominance, especially given Qatari plans (announced a month before the Saudi blockade) to vastly increase natural gas production by removing drilling restrictions.

If oil prices and the Saudi economy declines further, it is possible that Saudi hawks may take more drastic measures. We've already seen a major PR campaign against Qatar by Saudi media as part of rising tensions between the two Gulf countries. All Qatari media, including Al Jazeera, has been blocked in Saudi Arabia and the UAE. (Saudi's excuse for the ban was that Qatar's leader made a positive comment about Iran which he probably did not make.)

If the region moves toward direct conflict, Turkey will likely stand with Qatar, since the country has a substantial interest in running pipelines from Qatar's gas reserves in the future as well as relatively strong historical ties.

When the current showdown began, Saudi Arabia and its allies issued a list of 13 demands on Qatar (i.e. shut down Al Jazeera, remove a Turkish military base, pay reparations, etc.) that were virtually impossible for Qatar to meet. Then, shortly after Turkey began sending troops to Qatar and its president began preparations for a diplomatic trip to the region, Saudi Arabia and its allies appeared to reduce their list of 13 demands to "six broad principles," suggesting that they were, perhaps, unwilling to risk a direct conflict with Turkey. US Secretary of State Rex Tillerson has also been calling for a lifting of the anti-Qatar blockade.

But on Sunday, Saudi Arabia returned to demanding that its list be obeyed and accused Qatar of having made a "declaration of war" by demanding that the Hajj pilgrimage be internationalized. (Confusing matters still further, there's been no evidence that Qatar made such a demand.)

Should the Saudi economy decline much further, it is unclear what will happen next. Sometimes, economic desperation can lead to reforms. Other times, it can lead to war. Hopefully, we'll get the former rather than the latter.
