I don't see what that has to do with the current shortage as the main bottleneck is with refining oil, not extracting/transporting it

That obviously did not make a difference now because it wouldn't be in use and the issue seems to be refining more than oil supply.

I think you mean they Keystone XL pipeline. The Keystone pipeline has been running and Biden didn’t cancel it.

Keystone XL is a zombie project which abandoned by the development/infrastructure company. It had been stuck in regulatory review and litigation for a decade.

Environmental reviews by both the Obama Admin and Trump admin state that Keystone XL would not have lowered gasoline prices. You are pretending like all oil/gas products are fungible, when in reality most refineries in the US are not capable of refining all raw product. Hence “Energy Independence” is purely a marketing term and we still need to export lots of raw material and import other kinds of raw material to match what we are capable of refining.

a pipeline that wouldnt even be operational yet?
