The politics of North Korea takes place within the framework of the official state philosophy, "Juche", a concept created by Hwang Jang-yop and later attributed to Kim Il-sung. The Juche theory is the belief that through self-reliance and a strong independent state, true socialism can be achieved.
North Korea did not always have an official philosophy.
Relying on the information in the context, we do not know whether they did or didn't. From its birth, North Korea may or may not have had an official philosophy. I think the system made an assumption that they did not, which it could not guarantee just from the context.
