Islam isn't any more inherently insane than Christianity or Judaism. The problem is a lot of the cultural/tribal baggage they add onto their beliefs, and the general poverty and lack of education in the middle east. Extremist groups can take advantage of this, because the people aren't given critical thinking skills, and they can blame their poor living conditions on "the infidels". The governments aren't going to do anything about it, because the problems are largely their fault, and they're not about to let the blame shift back to them.
