And, of course, their boss--the king of hell--has been scheming and strategizing this end times era for millennia.
They know that specific long range planning does NOT work. However, they set up many puzzle pieces and forces toward their goals and adjust as situations require along the way--always more and more, closer and closer to their END GAME.
They are masters at playing all sides against each other; setting up factions and conflicts between interest groups; divide and conquer etc. etc. ... always with more and more tyranny whenever they can get away with it; always with more and more suffering whenever they can get away with it; more !!!CONTROL!!! whenever they can get away with it; more abuse and slavery etc.
Never doubt they DO HAVE a plan--lots of plans. And they can move in and out components of various potential plans at will as circumstances change and require.
There was a time when I would have dismissed your post out of hand as a wacko conspiracy theory, no more. Is what you propose correct, I still tend to doubt it. But I know accept that you could be right. I still think simple greed is a better explanation. However, consider the history of international communism in the last century. Many people acted to further the cause without profiting directly. What you propose would require the same sort of true believer. Could a conspiracy like you describe motivate the same sort of loyal adherence, it is possible I suppose.
