this is the mesoamerican demoralisation strategy(not a real name), basically one of the reasons that south America was so easily conquered is because they believed their world was coming to an end, after the first contact a hundred or so years before things where going to shit and big time, real epidemics where sweeping the continent and whipped out 90% of the population, this coincided with astronomical feature they considered holy(pretty much there heaven if im remembering right) no longer being visible at night due to the changing sky its kind of like predicting programming combined with religious zeal and some real serendipity (although not random chance, the ancients where smarter than people know and the earth follows cycles which they knew about better than people today) it makes for a nasty combination that made them really believe that their world was coming to an end, (((they))) have been trying to do it in the media for ages, they learned from the america military who where the biggest player in that regard, before (((they))) reached a higher power level because i just cant resist one of the ways aztecs said the world ended(because back then your "world" was a lot smaller and the collapsed of civilisation or the destruction of a few tribes means the end of the world) was by jaguars which sound absurd but if you think about it its possible, a shift in the climate causes a population boom of jaguars, they hunt their way closer and closer to an early society that is facing famine and eventually when other food sources are exhorted they start making bolder and bolder attacks on people, now think about how that applies to giving a large amount of aide to africa
