Vidiot ... you are right of course, but I'd add that its because of ignorance that devout Witnesses allow themselves to believe in the Governing Body.
I have learned that the more that a person really studies history (not just superficially skimming through it), the more a person understands that war, famine and pestilence are mankind's constant companions ... and in some ways, their appearances not chaotic at all.
There is a term used by historians and political commentators sometimes ... the long peace ... that helps to describe the peace the modern world has enjoyed under Pax Americana. It was real. But now that America is a declining empire, 'the dogs of war' are once again slipping their chains. Call it a power vacuum, a fourth turning (see Strauss–Howe), call it whatever, but the world goes a bit unstable at the end of a world power's domination. It happened at the end of all the classic world powers that we know of ... and it will happen again.
So in many ways it should be expected that the weak, the depressed and impressionable will begin to feel like they are drowning in fear and be full of anxiety over the future. And like any drowning man, they will naturally grab hold of anything floating around them, even if it is a piece of rotten old wood ... or a insincere religion.
