Some have even gone as far to say Herbert modelled Dune after the struggle between the Sunnis and Shiites.

No I think Dune is Arab city dwellers vs Bedouin natives.
But in any case off topic ?
I think its funny that even though I caught all this growing up under Reagan made me overlay on the drug war not oil.
I graduated high school in 1986 and had no perception of oil as anything important it just existed.

I know this is a bit off topic but I think its important to some extent since most of the people my age literally can't think of oil as important by default we have never seen a oil crisis that impacted supply at best gasoline is a tad expensive. This was my view point before I stumbled on peak oil. And now everyone knows how old I am :)
