We can define propaganda in contrast to psychological warfare. Whereas psychological warfare is the dissemination of cultural products by a military to the population of a foreign adversary in pursuit of a strategic objective, propaganda is the dissemination of cultural products by a government to their own people in the pursuit of strategic objectives. This definition serves the discussion of propaganda in the broader context of warfare well.
That would be considered propaganda. I was too strict by claiming propaganda can only be done to a government's own citizens.
In contrast a good example of psychological warfare would be when Russia organized a protest and an attendant counter-protest in Texas that were made to appear "organic."[0] So the difference between the two is that one proudly has an official "Russia" label on it and the other is clandestine.
