If you really want to see mass psychosis close up and personal, then read this:
There are people running around the Middle East who believe this kind of stuff with the same fervor as they usually reserve for their religion. These people eat this stuff up like it was coated in chocolate.
This is not merely a matter of having "better propaganda" than the other side or merely doing a better job of "getting our message out" or any other euphamism you can think of along those lines. This is simply the result of a culture that has gone completely beserk and which has no means of comparison with the outside world.
There's only two ways to deal with this kindof sick culture: it either requires time, treasure and blood to change people's minds (a very slow process), or you kill them before they kill you.
