Similarities;

Both are jehads. Frank herbert robbed off islamic mythology

'He who controls the spice controls the universe.' <--> oil

Both need a messiah

CHOAM <---> world trade organisation/IMF/AIIB

Landsraad <--->UN, Nato...

Sardaukars <---> US, nato troops

Difference:;

No sand worms

Freuding parties are iran/saudi arabia,  not quite the same as harkonnens/atreidis

Similiar as well as different: Assign the arakis governorship to raban <---> assign the governorship of iraq to the shiites

Conclusion: The Mother of all Jehad is coming. I'm convinced Fremen are truely terrorists in the 20th/21st century sense of the word, they want to destroy the old order
