I always thought of America as the Harkonnens, but now that you said it I realize that we are the Imperium, OPEC is CHOAM and Saudi Arabia are the Harkonnens.

The fictional Spice (Melange) is used by ordinary rich people to live longer. More importantly since their culture has rejected the use of AI they use much larger amounts of Spice to give the Guild Navigators sufficient foresight to be able to pilot Highliners through space-time, enabling the empire to cover a number of star systems.

Or a reference to the 1965 novel Dune, if you're lucky.

Given that the phrase doesn't appear anywhere in Frank Herbert's novels (the horrible dumpster fires by his son may have it, but I couldn't say), it's certainly a Lynch reference.

But my question wasn't what "spice" means, I assumed everyone on Hacker News knows that.

I was asking why Saudi spice is particularly relevant to US interests, when we're a net exporter of said spice.

It was admittedly a bit tongue in cheek; dramatically reduced Saudi supplies would impact energy markets in a bunch of second and third order ways we might not like.

But that doesn't mean we have to keep selling them guns.
