Well, in essence, propaganda is advertising. And advertising leans on satisfying perceived need.
So if I’m selling you shoes it’s to satisfy your physiological, social, or self-fulfilment order need. Shoes are functional, make you cool, or make a statement.
Propaganda is fulfilling some need to be effective - probably fear based in the social, safety, or belongingness orders, and carried via viral channels like word of mouth or social (viral).
I haven’t really thought about it too much but it’s just a communication or a reinforced message; it’s just advertising. Think about it that way.
And with regard to Russia, they are all ‘fear the West’ and ‘national pride’ driven, compounded over 3-4 generations. It would be such an easy spin.
