The facts: the Middle East is in turmoil, and the US has already been drawn into the conflict. They are desperately trying to conceal the degree to which they are involved entirely because of oil. Today, it was leaked that more than two weeks ago, the US camp came under attack by a drone, saved only by the fact that the explosives didn't detonate.
Speculation: I think Biden has his financial wizards working overtime to suppress oil. "Get it down boys, we have a big problem coming up that's going to affect the price"
Iran has seen Biden's hand. He is afraid to do anything that will interfere with oil trade, and is avoiding everything that might force him to restrict oil trade as a punishment. So Iran and its allies are taking liberties with the US and their allies. Now Iran has gone too far in some way unknown to us and Biden hast to do something at the urging of his own advisers, as well as other countries leaders.
So the plan is to get the oil price low before they impose sanctions/embargo.
The price of oil is a major threat to Bidens, political future. He is going to throw everything he can at it, but now finds himself stock between a rock and a hard place.
