Comrades, help me understand Juche please!

Howdy y'all!

A few years back, I did a deep dive into the history and politics of the DPRK, but the one thing that I struggled to wrap my head around was The Juche Idea, and I'm wanting to jump back in and try again!

So, what are the main principles of Juche?

How does it compare to other ML variants in the rest of East Asia/in general?

I once saw Juche compared to existentialism. Is that accurate?

Any resources to help me learn more? Most of what I've found has either been old, difficult to understand, translations of old DPRK books, and uncritical regurgitations of those old books with little in the way of commentary.
