@Quasit @HamonWry There are too many parties with a variety of interests, any one party such as a the US, controls so little of the supply chain to be able to really control it. It is way easier to destroy, make the price of oil to up, than to provide redundancy, sure up supply chains. If he is going to make oil prices go up he could at least invest in renewables in the US and ditch the stupid giant pick up trucks tax breaks, but his donors and Putin wouldn't like that.
