That's why I said either inept or too smart for their own good because closing of the strait was a real threat before the war and was ignored, leading to the tweet on Easter.

Even if US refineries were designed for US oil to keep domestic prices low one would have to introduce export restrictions because oil is a global commondity. Big oil will not be happy about that and it seems they have a great influence over the respublican party and Trump.

Oh I expect its a very real possibility that the oil industry would just be nationalized if push came to shove.

I don't expect this to happen given how powerful is oil lobby in the US. At least not when Republicans control house and senate.

Nationalization doesn't define who is in charge though. You can have the state taking over industry, you can also have industry taking over the state. Both ultimately lead to nationalization of the industry.
