Surely we have our own terrorists ? I'm a former terrorist, calm down GCHQ & NSA, because I was in the UK military but our form of terrorism is acceptable because we are the good guys ! My dad was also a terrorist because he was a solidier in WW2, he never spoke about the horrors he must have witnessed.
Religion and politics are both tools used to recruit terrorists, as is nationalism.
What a messed up world this is ! And we are led to believe that we are the most intelligent species on the planet !!! I would strongly disagree. I would argue that we are the least intelligent species on the planet !
