Video apparently exposing western propaganda… from North Korea?

This is a Korean or a North Korean documentary which goes into detail about exposing western propaganda from roughly England in WW1 and again in WW2. I am pretty sure it exposes how after WW1 the Brits gave up their propaganda program whilst the USA continued theirs and to this very day. I can’t explain too much about the video as I have just started watching it myself.

There are 6 parts which have been released but i am not sure about the final 4 parts just yet…
