>> that is north korean propaganda coming from the propaganda village. you may have seen the flagpoles. >> bret: it's a song we are supposed to like north korea after we hear it? >> absolutely. oddly enough they boastfully had propaganda broadcasts from either side. it stopped in 2004. in 2015, there was a provocative land mine incident up here, and it blew off two infantry division soldiers' legs. ever since then, both sides have been pumping the propaganda again. it can be lovely music like this or it can be speeches. north korea plays at about 20 hours a day. on our side, we do two or three hours a day. anything from news broadcasts to k-pop. they were playing radio free america.
