Yeah, this is also how I'm thinking. Squeeze China directly (over supply) and Europe indirectly (over price) while helping Russia. Russia was having difficulty negotiating a pipeline with China, but they're in a much stronger position now, and their oil export profits have recovered from the Ukraine refinery attacks.
That's why Saudi Arabia, etc. are/were on board, since it also drives up their own profits if the price goes up. Kushner and the prince kept meeting up and discussing this sort of thing prior to the war. Two peas in a pod.
Before the Iran War, oil was cheaper in real terms than ever before, and now look at the price. Price of oil is everything.
