Well, p'raps I spoke too quickly. I too once dreamed that the roots of terrorism could be found and healed. I do believe that a great deal of very poor-grade thinking has to be in place before a human being will strap on a suicide vest, or even take up an Kalashnikov against another human; unlike some poeple I do not think it is innate, this proclivity for violence. It is born out of real or imagined desperation.
Imagined desperation, of course, is born out of imaginary situations, which requires being willing to let go of imagined realities and deal instead with what is before one. Not a popular notion in some parts of the world.
But there are also a lot of situations causing real desperation in the lives of humans connected with terrorism.
If they had an abundance of water and energy, and access to information, they could probably turn any of them around if they were free to act. Of course, that means some folk have to let go of their captive audiences and ensorcelled minions. Another unpopular idea.
