Worth noting that earlier this year US imports of Saudi Oil hit zero. Granted it was just for one week but certainly reflective of the broader trend.

Even before the shale oil, US had no problem to expand its oil production to match its own consumption.
What prevented US oil industry to just work was a very strange regulatory framework where it was both shielded from competition, and prevented from expanding, keeping it in subservient role as a supplier to US strategic petroleum reserve.
For all intents, and purposes the US legislation only benefitted Saudi interests after 1975.
Now that we have shale, it seems like this policy is less worth it.
