The history is a bit more complicated then that.
Korea was occupied by Japan for like 20 years and then arbitrarily divided after WW2.
There were people committees formed in the aftermath that were largely anti-collabrator, pro-peasant/worker and wanted land reform.
The American and Soviet occupations both tried to deal with them and while I don’t know if the Soviet’s handling of it was perfect they did make some attempts to integrate them while the Americans and the south outlawed them.
What happened in Korea was and is much closer to a civil war than an invasion of a foreign force, especially in 1950.
