Just my two cents worth, but the core problem with the jihadist mentality is rooted in a belief system that is dying along with fundementalist Bible based belirf systems...they are part of an old religious thought form and they are fighting like wild animals to stay alive all the while being penned in by evolving spiritual ideals and social structures that label them as barbaric.
And they are IMO.
But they will keep breaking out and killing and hurting people until they finally die.
Personally I look at these things as acts perpetrated by very unevolved people but time will tell...survival of the fittest anyone? I certainly hope that love and compassion prove to be stronger in the final outcome. Sometimes it feels like common sense and goodwill are losing the battle but although a few persons who commit heinous acts make the news there are many acts of kindness and compassion happening that don't make the news.
Yes, survival of the fittest!
