On a more general level, I think we (as in any society that's not too far gone like Russia) need to educate our young about propaganda and how to not fall for it.
Social media has been a game changer in terms of the spread of propaganda, if nothing is done about that then I fear we'll see the end of humankind in our lifetime.
