Laos really hasn't put anything revolutionary regarding theory-wise, and combined with the fact that Laos never really was unique among its other nations (China with Socialism with Chinese Characteristics, DPRK with Juche), it just kind of fell into obscurity for the most part.
Nonetheless, it would be ideal to study this as long as we got theory for it. Unfortunately, the theory is sparse or hard to find, meaning that we don't really have a solid basis.
While I'm not entirely sure, I imagine it is due to a combination of it being a tiny nation and it being one of (if not the least) developed nations in the world due to Amerikkkan bombing. I would love to hear more about it though.
Even worse, it's the most bombed country in history. Over 270 million bombs were thrown on Laos from 1964 to 1974 (a planeload of bombs every eight minutes, 24 hours a day, 9 years long). Something like 80 million of them didn't go off, making life difficult to this day, because they're still there.
You'd think so, but CIA happened and now it's another crapitalist country; despite the socialist motif. Even its socialist party (the MPLA) got turned from a Marxist-Leninist party to a Succdem one.
