Do we have the refinery capability to manage a war?
Yes the US does, depending on how you look at it.
US refinery capacity is @18.5 (some say 18.9) mbpd, equivalent petroleum consumption (refined products entirely) is @20 mbpd
So US refinery capacity is >@90% of US peacetime consumption.
The US is a net importer of refined products, but only on the margins.
However, in wartime there will be domestic rationing, affecting the bulk of actual refined products consumption. Unless the US has to support a vast array of foreign allies (WWII all over again), at the moment the US is good with refinery capacity.
That’s the big takeaway
Logistics.
Time is lives.Its instant defeat.
