We used to have absoltuely vast underground resveres of oil, diesel and gasoline in this country.

Why?

1. The military was obsessed with bunkers of all kinds. This country looks like a Swiss cheese.

2. The military and the government was preparing for the last war, WW2, when we were cut off from oil imports for several years.

Actually, during the absurd "missing barrels" episode 10-something years ago people were speculating that all these (later understood as entirely fictious) missing barrels that depressed the oil price to under $10 were hidden in undreground bunkers in Sweden.

The rationality of the market...

And the rationality of government: all that oil was sold at bargain basement prices years ago.

Peak oil is not an energy crisis. It is a liquid fuel crisis.
