I believe you are underestimating the importance of Biden refusing to speak with the Crown Prince as he called world leaders as his term began. It might seem just symbolic but it's much more than that.
Also the oil dependency graph can change during resource-intensive conflicts.
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.
