This new “bunker video” is just one more tactic in the WT organization’s arsenal for the sole purpose of promoting the one thing which has served them well all along: FEAR!
They used to portray imagery of Armageddon in the artwork in books, most notably the big orange book from the 1950s called From Paradise Lost to Paradise Regained, depicting all the non-JWs, including little children and even their pets, falling into large crevices opening up in the ground. (The images of those truly evil and manipulative drawings have been indelibly imprinted onto a lot of young, impressionable minds for life!)
But now, it would seem that people are less scared of the idea of God acting in that way, as people probably don’t identify with it as much in this secular, technological world. So, instead of focusing on some miraculous, supernatural worldwide destruction, they’re instead now trying to instil a kind of fearful scenario which is more plausible and hits home more effectively by playing on people’s fears of a rogue government and anarchistic social disorder.
That kind of fear is more effective because instead of involving an abstract and enigmatic deity, such as an angry and vengeful Jehovah, the fear relates to elements of actual real life which we know exist and we can see – that is, people comprising things like governments, the police and the military (or a militia), etc. Such elements and factions of human society do indeed at least exist. They are tangible. And thus a manufactured fear of those things going terribly wrong is more identifiable and effective.
A horror movie involving an ordinary house in an ordinary neighbourhood seems more frightening than a movie about a clearly fictitious and fanciful setting, such as an alien planet in some other galaxy. The sort of “horror film” which is the current convention “bunker video” relates to a theme that is familiar and identifiable – which is the perfect new venue for the new round of manipulative fear mongering for which the WT organization is so famous.
