on rational evilness

Researcher Hans Brun helps us grasp terrorism as a phenomenon.

It's not new, the first "wave" occurred well over a century ago. And it's not irrational. On the contrary - terrorism is a conscious choice made by rational actors, says Hans. It's a strategy serving specific purposes. Terrorists aim to create chaos, provoke an overreaction and portray themselves as a credible and legitimate power.

Deconstructing terrorism won't make it any less ominous, but it helps free societies find defensive strategies.
