> The US is also the second largest oil importer in the world.

The US sells oil refinery services to the rest of the world. They "import" crude oil and then "export" the refined product.

US refinery capacity far exceeds its domestic oil production. What did you think they were doing with all that capacity?

This is not as simple as you present it, which is why we import about 70% of our jet fuel from South Korea.
