The war is about the LNG pipleine from Qatar to the Med. The Saudi’s want this too. The Russians, and by proxy Assad, do not.
If the pipeline goes in, the Russains lose influence on Western Europe via energy.
The Qataris’ plan goes forward, and the Shiite’s win. Saudi plan goes forward the Sunni’s win.
Follow the money.
Western Europe desperately wants to get a LNG pipeline around Russian control to keep the lucrative energy profits in the West.
They would love a war between Russia and the US where they profit in multiple ways and the US gets death and debt as reward for being suckers.
That makes more sense than anything else.
