The article seems mostly fine, but I think it's putting the cart before the horse. You don't destabilize your oil supply because you're greedy for oil, that just doesn't make sense.
The purpose of capitalism is not profit, the purpose of capitalism is empowering the rich. Profit is a means to that end, and one that is regularly discarded when the most profitable move is to let power be decentralized. For example, any company outside the healthcare industry would profit massively from universal healthcare because it dramatically reduces attrition in their workforce while costing less than privatized healthcare meaning taxes on their company could be lowered. But rather than lobbying for universal healthcare and increased profits, companies stand in solidarity with their fellow companies in the healthcare industry.
The idea that capitalism is simply pursuing personal gain so it would be irrational of them to be kind is yet another capitalist lie to excuse deliberate oppression. The goal of the invasion of Iran is not to profit, the goal is to crush Iran.
