Use the perspective that describes why we have Terrorism and Blow Backs, do not question the terrorists actions but instead try to understand the actions of the terrorist, try to analyze his behavior and reasons for his actions, both on a individual level, but also on a higher echelon organizational level.
The reason to why the Swedish (as well as the rest of the western) populations are so ignorant and "stupid" in world politics and in the understanding of grand strategic and tactical perspectives, is due to the fact that they just don't have the necessary capacity, skill and knowledge to understand items future away from their own perspectives.
Terrorism is a very natural thing, we can discuss forever if it is just or not, but the point is that it is not something new, and it is not anything who is "hard to understand". It is however very hard to understand for most individuals due to lack of basic knowledge and understanding of how the world works.
So, learning how the world works is the key to understanding Terrorism - and you wont be able to get that down and into a 4 pages rapport.
