I don't mean to be cynical, but the Juche idea resembles buddhism...
Sure it does, especially under the influence of some serious psychedelics!!!
Juche is a materialist/nihilist social and political doctrine based on Marxist-Leninist ideology. It was devised by Kim Il Sung in order to justify his brutal dictatorial regime and turn himself into a secular god. It was used by Kim Il Sung, as an effective propaganda device, to remain in power even though he was basically responsible (due to his intransigence around the issues of self-sufficiency and zero reliance on foreign powers) for the deaths by starvation (and associated illnesses) of somewhere between 1-2.4 million North korean citizens during the mid 1990's.
Identical to Buddhism, I would say!
Not that the North Koreans do not deserve our sympathy and prayers, of course they do, but there is no need to look for similiarities where none really exist. Compassion is for eveybody/thing regardless of similarities and differences.
