The thing that is hurting Saudi Arabia is that with the price of natural gas taking a massive nose dive (and refineries all over the world are preparing to refine gasoline, diesel fuel, and lubricants from natural gas on a truly massive scale), the Saudis can't rely on crude oil exports anymore. However, the Saudis still have massive natural gas reserves, but it will take time for Saudi Aramco to build up the gas production and export infrastructure (something that Qatar and Iran have heavily invested in).
In fact, if I were Iran, Pakistan and India, I'd hold a summit and produce a gigantic deal to export natural gas from Iran to Pakistan and India through land pipelines. Not only would Pakistan and India now get a relatively clean energy source, but it would stick it to the House of Saud (which in turn could put the political screw on ISIS).
