“Oh, do wipe that childish look of confusion off of your face, Kathryn. Whatever the man’s faults may have been, and many they were, his choice of drink was exceptional. You? You’re but a half-step away from boiling kidney and navy beans!”
I must not Lwaxana.
Lwaxana is the mind-killer.
Lwaxana is the little-death that brings total obliteration.
I will face my Lwaxana.
I will permit her to pass over me and through me.
And when she has gone past I will turn the inner eye to see her path.
Where the Lwaxana has gone there will be nothing.
Only I will remain.
The name Harkonnen (though Finnish) was chosen because it sounds Russian. However, no, it isn't really a US VS Soviet story. It's about systems. It's about ecology, power, and freedom. If you only read Dune then I can see how you could think that, but the other books give you a lot more information.
Arrakis is terraformed, and this disrupts the ecosystem of Shai-hulud, which destroys spice production. It also destroys Fremen culture, with people teaching what the Fremen were like, but not really knowing.
Paul and, to an even further extent, Lato II are aggressive dictators. They destroys people's freedom, with the end goal to create people who can't be predicted who rebel, because that's the only way (that they can see) to guarantee freedom for humanity.
I addition to this, the Harkonnen are really just there as a subversion. Paul's grandfather, as he learns in Dune, is the Baron Harkonnen, so he is a Harkonnen. This really destroys any message about it being one side VS the other.
It's about systems. Paul was systematically bread. The Harkonnen and Atreides were used by the emperial system to maintain control and order (although this failed). The system of ecology keeps Arrakis in balance, and the people live in harmony with it. Systems of control prevent people from being free.
Probably, but history repeats itself. That conflict was not the first time the line between business and public interests was muddled with the result of large scale warfare and oppression, nor the last, so the same themes are relevant. And the meme has a very explicit focus on tea.
